The K.Top: 18,000 digitised maps and views released

Add comment

Today we release 18,000 digital images of historic maps, views and texts from the Topographical Collection of King George III into the public domain.

The collection has been digitised as part of a seven-year project to catalogue, conserve and digitise the collection which was presented to the Nation in 1823 by King George IV. This is the first of two planned image releases.

The images are made available on the image sharing site Flickr, which links to fully searchable catalogue records on Explore the British Library.

For the first time, anybody who wishes to can remotely view, search, research and enjoy one of the world’s richest and most varied public collections of the history of place.

The idea of remote or virtual travelling is a particularly common one today thanks to the seamless interfaces of online map viewer that simulate the idea of airborne travel and evoke the excitement of discovery. However, the idea of virtual travel has a long history, and is well illustrated by the travel-averse king who resided in his palaces and viewed the world through his collection of maps and views. This is the Google Earth of the late 18th century and the journeys it can take you on are no less informative, intriguing, and instructive of the many facets of past eras.

 What is K.Top?

The King’s Topographical Collection (K.Top) is one part of the Geographical Collection of King George III (the other parts are the Maritime and Military collections). The nucleus of the collection was assembled from 1660, but added to considerably after 1760 by the king’s librarians and agents. The collection was presented to the British Museum (from 1973 British Library) as a distinct part of the King's Library in 1823,. For more on the history of the collection see this post by Felicity Myrone.

What is in it?

It’s probably easier to list what isn’t in this collection. It totals around 40,000 printed and manuscript maps, views, charts, texts, architectural plans, prints, atlases and ephemera. The collection is arranged geographically, with around 40% dedicated to the British Isles, one third covering the Europe of the Grand Tour, and 10% for British areas of influence such as North America, the West Indies and India.

 What themes does it include? 

Too many to mention, but here’s a sample: landscape, tourism, antiquarianism, architecture, rural life, fine art, agriculture, medieval and church studies, urban planning and development, industrialisation – canals and transport, military history, the history of collecting, the history of cartography, the Grand Tour, royal palaces and stately homes, science and invention, the history of exploration, American Independence. 

As a product of the 16th-19th centuries, the collection is also associated with imperialism, and the role of maps in facilitating imperialist activities both practically and ideologically. We hope that the release of this material will facilitate research and greater understanding of these aspects of the past.  

How can I access it?

18,000 images are available via the file-sharing site Flickr, which you can find here https://www.flickr.com/photos/britishlibrary/albums/72157716220271206

Images from the collection are also tagged George III Topographical Collection https://www.flickr.com/photos/tags/georgeiiitopographicalcollection

Maps and photography: a brief history, part 3

Add comment

This final chapter discusses a number of cartographic innovations from the middle of the twentieth century onwards that exploited the ability of photographs to capture data - from developments in aerial photogrammetry, through multispectral satellite mapping and surveillance imagery, to the digital map platforms of today.

Technical innovations that had begun during the Second World War soon extended into the civilian sphere with the widespread adoption of aerial photogrammetry by national mapping agencies worldwide – a development that arguably had a greater impact than any other on mapping practices of the twentieth century. New radar surveying techniques allowed air photographs to be pinpointed on the ground more accurately, more economically and over far greater areas than before, bringing vast regions of inaccessible terrain within the mapmaker’s scope for the first time.

Between the 1950s and the 1980s, the whole of the Soviet Union was mapped in this way, resulting in over 300,000 sheets at a scale of 1:25,000. During the same period, the British Directorate of Overseas Surveys also covered over 2.5 million square miles of land, mostly over former British colonies and administrations that had no mapping capability of their own. The image below shows an isolated settlement and nearby areas of subsistence agriculture in eastern Nigeria. Maps made from such images contributed to state economic and social planning initiatives.

Mapping vast, sometimes featureless, inland regions led to some eccentric examples of cartography. The following detail is taken from one Australian map sheet that covers more than 2,750 square kilometers of the Great Sandy Desert. Each square is one kilometre on the side. Of the total 3,062 sheets in the series covering the whole country, only half were printed – this sheet was selected for print on account of a single track that meanders briefly along the bottom edge, before diverting back to the adjacent sheet beneath.

Widespread use of air photographs also led to security concerns. As part of the British reconstruction effort after the war, the RAF covered the whole of Great Britain with aerial photography in order to assess bomb damage. Between 1945 and 1951 the Ordnance Survey published the photography as OS Mosaics, large-scale rectified photomaps of towns, cities and some rural areas.

After many images had already been published, it was feared that foreign states might benefit from the level of detail of sensitive sites that was revealed. Further editions of the same sites were therefore over-painted before publication in order to remove or disguise these features. The military airfield shown in the image below has been replaced by a fictitious pattern of fields and country lanes in the later version beneath. In 1954 OS Mosaics were removed from sale entirely.

An alternative and innovative approach to photomapping was taken in Sweden. From as early as 1935, aerial photography was incorporated into the Ekonomisk Karta land use series. The large-scale photographs provided a base layer onto which topographic, cadastral and land use symbols and colours were added.

Stereo pairs of air photographs could be made into three-dimensional ‘anaglyph’ images, which were viewed through coloured glasses. Examples of these were created for military planning purposes during the Second World War, such as a German series from 1944 showing the Istrian coastline (held at BL Maps Y.3842.). After the war, the French national mapping agency published a number of anaglyphs in a Relief Form Atlas of 1956. The purpose of the atlas was to teach readers to understand the mapping of a wide variety of landscapes by showing three-dimensional views alongside maps of the same location. The following image of the volcanic cone atop Mount Karthala in the Comoros is striking when viewed through a pair of red and blue 3D glasses.

Images taken from aeroplanes were soon joined by those taken from satellites, after the launch of Sputnik by the Soviet Union in 1957 sparked the Space Race between themselves and the USA. The speed of technological developments over this period is encapsulated in the three images following. This annotated photograph taken from a military aeroplane in 1936 captures the curvature of the Earth for the first time, and shows the highest point then reached by man.

Photograph showing the curvature of the Earth

Only two decades later an unmanned Russian spacecraft, Luna 3, took the first pictures of the far side of the moon as it orbited in 1959. The images were transmitted back to Earth by radio link and published in Moscow the following year in the Atlas of the Far Side of the Moon.

Within the next ten years man too had travelled round the moon. American astronaut William Anders took this iconic photograph, which looks back at the Earth as it rises above the lunar surface – an image of the world that had previously been possible only in the imagination.

Both the Soviet Union and the USA launched military reconnaissance satellites during the early 1960s that were capable of creating high resolution imagery for intelligence and mapping purposes. Civilian satellites followed, perhaps the most successful of which was Landsat, launched by the USA in 1972.

Multispectral satellite imagery became an essential feature of land survey and resource management, leading to a proliferation of thematic maps, and a new category of mapping under the title satellite image maps. The ease with which satellite imagery could track changes over time in the environment also brought new insights to many areas of study, including urbanisation, de-forestation, analysis of weather systems, and ocean dynamics.

Nowadays aerial photographs and satellite images are ubiquitous in digital mapping products that have become a common feature of everyday life. 2001 saw the launch of Google Earth, an application in which satellite imagery and aerial photography are draped over digital terrain models to provide interactive three-dimensional map views.

In other applications, maps and photographs are now interchangeable - users can choose between map or satellite viewing modes.

Google Street View, launched in 2007, integrates terrestrial photography and cartography to create a model of the world from a horizontal viewpoint – a mode of representation with antecedents in artworks of former times. In the early 1900s, Eugène Atget started to make images of the older parts of Paris with the intention to record streets and buildings that risked being torn down and re-developed. By 1920 he was able to write, ‘This enormous artistic and documentary collection is now complete. I may say that I have in my possession all of Old Paris’.

Half a century later, American artist Ed Ruscha created an artwork entitled Every Building on the Sunset Strip by fixing a camera onto the back of his truck and driving up and down as it took pictures on a timer. His intention was to recreate the experience of moving through the landscape.

Google Street View now also employs cameras fixed to cars, or strapped to pedestrians’ backs, to create strips of 360-degree images stitched together. The artistry and focus on aesthetic have been lost in these pictures made by machines, but those qualities have been replaced by functionality. Google’s georeferenced, navigable imagery allows users to search and interact with a vast database of (mainly business) information. The corner building shown below, tagged so that one can choose to see the menu or make a booking at the restaurant within, is the same as that in the Atget photograph from 100 years before.

The perceived realism of digital maps and photographs makes them particularly persuasive. However, two posts reproduced from Twitter, below, document conflicting facts about the shooting down of an American drone by Iranian forces in June 2019. The first, published by US Central Command, shows the drone flying through international, not Iranian, airspace when it was hit, while the second image, posted the following day by the Foreign Minister of Iran, shows the drone in a different location, within Iranian airspace.

This incident reminds us that the latest generation of maps and images remains as susceptible as any before to manipulation or exploitation.

Today more than ever, maps and photographs go hand-in-hand in our ceaseless attempts to capture, model, and mould the world around us.

World Map World Cup: Group 4

Add comment

We have come to the fourth and final qualifying group of our British Library world map world cup, and in it we have four extraordinary and breathtaking examples of cartography from between the 11th and 20th centuries. I hope the following descriptions, links and images will provide you with what you need to make your difficult choice.

Vote for your favourite over on Twitter (@BLMaps). The top two maps will go through to the quarter finals tomorrow, Friday July 10th. 

1.Beatus of Liébana world map. Drawn in Burgos, Spain, between 1091 and 1109 (Add.MS 11695)

Blog add ms 11695

The 15 surviving 'Beatus' maps are included in textual commentaries on the Apocalypse of St John (from the New Testament Book of Revelation) written by the Spanish theologian Beatus of Liébana (fl.776–86). The British Library’s example, arguably more powerful and brooding than the others, is a diagrammatic image with powerful pictorial elements. These include fishes swimming in the sea encircling the world, the‘molehill’ mountains and the unforgettable image of the Garden of Eden at the top of the map, in the east. It was produced in northern Spain (in the monastery of San Domingo de Silos) in around 1109, and as a result reflects Islamic pictorial influences that had spread from northern Africa.

2. The Contarini-Rosselli world map. Engraving, published in Florence in 1506 (Maps C.2.cc.4).

Blog maps c.2.cc.4

This is the earliest surviving printed map to show any part of the Americas. It was published in Florence in 1506, only a decade or so after Christopher Columbus's first voyage in 1492. The map, which is by the Venetian Giovanni Matteo Contarini and Florentine Francesco Rosselli, has been celebrated for its American content ever since this only known copy was purchased by the British Museum in 1922. But it is an extremely early and partial glimpse of eastern America: Newfoundland and Labrador are shown cemented on to Kamchatka, Cuba and Hispaniola are floating next to Japan, and South America is joined to the vast Southern Continent.

3. Aḍhāīdvīpa. Painted in Rajasthan in 1830 (Add.Or. 1814).

Add.Or 1814 blog with title

This is a map showing the structure of the world of Jainism, a religious system founded in northern India in the sixth or seventh century BCE. The map, which is in Sanskrit, was painted onto cloth in Rajasthan in 1830, and like many of the European medieval mappamundi, it illustrates a fusion of human and sacred geography. At the centre is the recognisable, terrestrial world of people (Mount Meru is at the centre, as it is in the Korean Ch’ ōnhado  maps). Surrounding it is the spiritual world: green concentric-ringed continents illustrated by lunar symbols and separated by fish-filled oceans, beyond which is the outer land of the jinas or prophets.

4. Self determination world map, by F. Klimesch. Published in Berlin in around 1919 (Maps CC.5.b.29).

Blog maps CC.5.b.29

The only 20th century world map to make it into our World Map World Cup competition (not that there aren't many great 20th century world maps, just a mere 16 places to fill), is a German map produced in the wake of the peace treaties following the defeat of Germany and the end of the Great War, 1914-1918. It shows the victorious allies Britain, France, Russia and the USA as soldier figures, holding leashes attached to their respective national beasts. These beasts have been placed over the colonies they controlled. 

The title explains why: 'What would be left of the entente if it made serious the right of self-determination of their own people and let go of the reins!' The map calls out the Allies' decision to confiscate German colonies under the principle of 'self determination,' but to retain theirs regardless. Given the century-long process of decolonisation that ensued, and ensues, the map is profoundly and powerfully prescient.

World Map World Cup: Group 3

Add comment

Welcome to Group three of the British Library's world map world cup competition, where you get to select our favourite historic world map for us. 

This group contains some astonishing artefacts from the last one thousand years, and I'm happy to provide further information on them  to help you make up your mind.

When you have done so, vote for your favourite over on Twitter (@BLMaps). The two maps with the most votes will go through to the quarter finals on Friday.

1. The Anglo-Saxon World Map. Drawn in Canterbury between 1025 and 1050 (Cotton MS Tiberius B.V.).

Blog cotton ms tiberius bv

For a world map containing such a quantity of information, the Anglo-Saxon world map is extraordinarily early. Much of this information relates to the Roman world: key walled towns such as Alexandria, Rome, Constantinople, the Pillars of Hercules at the bottom edge marking the limit of the world as known to Europeans, and lines marking the division of Roman provinces. Its genesis is possibly the first century map ordered by Julius Caesar. At any rate, the people who made the map would have felt themselves still to be living in the great Roman era.

2. The Martellus world map. Drawn by Henricus Martellus Germanus in Florence, around 1490 (Add. MS 15760).  

Blog add ms 15760

Henricus Martellus, or to give him his proper name Heinrich Hammer's world map is very similar to the 2nd century geographical picture presented by Claudius Ptolemy (see group one). But there are some updates. For example, Scandinavia appears, as do features taken from an account of the journey of Marco Polo. But the most momentous update is the one that shows the Indian Ocean not as an inland sea, but open, with the southern tip of South Africa navigable. Martellus knew this, because Bartholomeu Dias had sailed around it in 1488. The effect was to contest the hallowed ancient perception of the world, literally cutting part of the map's border away in the process.

3. Chinese globe, by Manuel Dias and Niccolo Longobardo. Made in Beijing in 1623 (Maps G.35.)

Blog maps g.35

This earliest surviving Chinese globe was constructed in Beijing by Italian Jesuits, most probably for a scholarly audience, in order to demonstrate geodetic principles such as longitude, latitude, meridians and parallels. Much of the globe, including large passages of text, derives from the giant world map by Matteo Ricci of 1602. But if you want to show things relating to the spherical nature of the earth, you really need a sphere in order to do it properly, hence the globe.

Geodesy had been known in China well before Europe, and we know that globes were also constructed before his one (though they have not survived), but such things were not part of Chinese culture at this time. The 'gift' of scientific enlightenment was used as a Trojan horse by the Jesuits to impose their religion upon China.

4. World map by Antonio Sanches, drawn in Lisbon in 1623 (Add. MS 22874)

Blog add ms 22874

This is an extraordinarily beautiful, large world map, emphasising coasts and navigational features. Delicate and elegant, blues and golds, painted and coloured with consummate skill. This indicates that it was not intended to go on board a ship. It presents the Portuguese view of the word, celebrating Portuguese influence well beyond Iberia with the Quinas (Portuguese arms) stamped upon areas as far afield as South America and China. The map also contains a significant (to say the least) quantity of religious imagery, the spread of Catholicism being a pillar of this world view, and violently enforced. Ironically, given the confidence this map oozes, by 1623 Portuguese dominance in world affairs was being increasingly contested by that European upstart, the Dutch.

Help us choose the British Library's favourite world map

Add comment

World maps are amazing things for their ability to conceptualise the earth and capture it in miniature. Of course, this comes at a price. World maps, perhaps more than any other 'image,' are powerful and subjective. Each one contains a particular world view, and throughout history they, or rather their makers, have tended use them to impose their views upon others. Who is at the world's centre? Who is relegated to the margins? Who is shrunken in size, and who is removed from the map all together? 

So it's a strange quirk of history that  during the 20th century, that most antagonistic of eras, the world map came to be seen as a symbol of co-operation, togetherness, shared heritage and environmental awareness (thanks in no small part to NASA's famous 1968 Earthrise photograph of our vulnerable planet hanging in the void). As a result, a world map is now capable of saying “we’re all in it together”. It’s World Population Day on Saturday 11 July, so let's attempt to reclaim some of that spirit.

I'd like to invite you to help us choose the British Library’s favourite world map.  Over the next week I’m going to introduce sixteen of the most extraordinary and groundbreaking world maps from between the 11th and 20th centuries, carefully selected from the British Library’s collection of over 4 million maps

The maps will be arranged into 4 groups, with one Twitter poll per day (Monday to Thursday) deciding which two maps from each group will go through to the quarter finals on Friday. The semi finals and final poll will happen on Saturday,  and we’ll think up something special for the winner. Follow us @BLMaps, hashtag #BLWorldMapWorldCup.

What selection criteria might you use? Well, did the map capture some signal shift in civilisation? Is it unique, beautiful, technically accomplished or cleverly made? Or do you just like it because you like it? That’s valid too.

Hopefully through this just-for-fun competition it will be possible to appreciate the history of a world of multiple viewpoints; and, though it won't be easy, to begin to rediscover ones which have been erased.

Maps and photography: a brief history, part 2

Add comment

The previous part of this article discussed the introduction of photography into maps and mapmaking over the first hundred years after its invention in the 1830s. Photography was initially used to complement information found on the map, by recording topographical views or objects of antiquity, and it was incorporated into the map production process from the 1850s. In this early period photographers also began to capture the work of survey teams in the field. Soldiers in the British Royal Engineers were specially trained in the use of cameras for this purpose. This group photo from circa 1860 was taken by one such soldier-photographer, and shows colleagues posing in a cutting cleared through the forest to enable survey work along the border between the United States and Canada.

Cameras were also employed to record advances in cartographic technology and instrumentation. The following scenes were set up to demonstrate use of the latest levelling instruments by staff at the Survey of India in 1909. Beyond this original purpose, the first image also illustrates the colonial hierarchy in the division of labour that was based on race.

Another later image demonstrates the same division of labour in Africa amongst members of the Anglo-Belgian Congo-Zambesi Boundary Commission, as European surveyors take observations from a trig point around 1930. A contemporary account of the survey published in The Geographical Journal highlights the pressure the Commission was under from the two European administrations to agree and demarcate this African boundary quickly, so that valuable mining rights could be settled between them.

After the First World War there was a drive to realise the potential of aerial photography in new fields of geographical and archaeological analysis away from the battlefield. In 1919 G.A. Beazley published an article entitled Air Photography in Archaeology, in which he described wartime aerial survey work carried out around Samarra in modern-day Iraq. The survey had revealed the layout of an ancient city, details of which were transferred to the military map, below, though they were evident only from the air.

Another pioneer of aerial archaeology was O.G.S. Crawford, who was appointed the first archaeological officer at the Ordnance Survey in 1920. He used air photographs made by the RAF to measure the length of the Avenue at Stonehenge, and later joined with Alexander Keiller to make an aerial survey of archaeological sites in several British counties. Together they published Wessex from the Air in 1928.

With the introduction of black and white infra-red photographic film in 1931, a new kind of geographical analysis became possible. Infra-red film responds to different wavelengths of light from the panchromatic type, and was useful in indicating high tide lines and different types of vegetation. The glass slide below shows an infra-red image from the 1930s, in which bare hills appear dark and sharply distinguished from the characteristically bright areas of cultivation at their feet. The water in the meandering river also shows up black.

With the outbreak of the Second World War the use of infra-red film was amongst a number of techniques trialled with aerial photography to map the gradients of enemy-held beaches. In the end, the most successful method used air photographs taken with panchromatic film to determine the shape of the seabed by studying the shapes and velocities of wave patterns as they came to shore.

This crucial element of wartime invasion planning appears in the following beach map of an island off the coast of modern-day Myanmar. The diagrams in red, on the right, were derived from air photographs and show the beach gradients at different numbered points on the map.

Photography fulfilled other roles in wartime invasion planning. During the Second World War German forces created volumes of geographical intelligence by country, in preparation for the invasion of foreign nations in Europe, North Africa and the Middle East. These volumes included photographs that complemented the information found on maps by giving a visual impression of the lie of the land, and by providing additional geographical intelligence. Pictures illustrating local geomorphology appear alongside images of industrial buildings, harbours and fortifications.

In the volume dedicated to the South Coast of England a number of what appear to be pre-war tourist postcards have been reproduced. The example below shows location 255 on the map of the Isle of White that follows. The accompanying text explains its inclusion - ‘Narrow sandy beach in front of the bank fortification, is exposed at low tide.’

Advances in aerial photogrammetry had continued between the wars with the invention of multiplex instruments in Italy and Germany in 1930, which allowed a single operator to map large areas quickly from small scale air photographs. In the United States the technique was adopted by USGS, the national mapping agency, and was widely used to map agricultural areas under New Deal public works projects, so that by the start of the Second World War a large number of trained photogrammetrists was available for the American war effort.

Many of these photogrammetrists were put to work creating photomaps of islands in the South-East Asian Theatre, producing innovative sheets that consisted of a conventional line map on one side and a rectified photomap on the reverse.

Similar advances had been made in large-scale aerial photogrammetry with the invention of the slotted template method in the United States in 1936. This was a development of radial line plotting techniques first promoted by the British Air Survey Committee in the 1920s, and provided a method of adjusting and correlating large numbers of overlapping air photographs.

One of the most intensive periods of large-scale aerial survey activity during the war came with the secret preparation of the so-called ‘Benson’ series of maps, named after the RAF station in Oxfordshire from which many of the survey and reconnaissance flights departed during 1942–43. The series was completed in advance of the D-Day landings in 1944, and features an overprint showing German defences along the Normandy coast of France. The British Library is currently conserving a representative set of materials used in the compilation of these secret maps, which will be made available at shelfmark BL Maps Y.4169. The material includes a US Army report that compares the accuracy of a sheet made by the multiplex method with one made by the slotted template technique.

Automated text extraction from colonial-era maps of eastern Africa

Add comment

After recently completing a pilot course in Computing for Information Professionals at Birkbeck University, I have just released a new dataset containing the text extracted from almost 2,000 colonial-era maps and documents covering eastern Africa. The resource is available now from the Shared Research Repository, and provides access to thousands of names of historical settlements and regions, descriptions of historical land use, topography and vegetation, and notes of ethnographic, military or administrative context.

Details of 'Umkamba Prov. part of (Central)', 1901 - BL Maps WOMAT/AFR/BEA/54 (above), and 'Masailand', 1901 - BL Maps WOMAT/AFR/BEA/41 (below). Transcribed words have been highlighted.

The resource consists of a downloadable spreadsheet, which lets users browse or search the extracted text. I hope it will be of particular use in identifying and locating place names in eastern Africa during the colonial period, for which there is a gap in current research resources. I’m also hopeful it will facilitate the contribution of these maps to studies of the history of the environment.

The text was harvested from maps and documents that are held at the British Library in the War Office Archive, a collection of over 14,000 mostly unique, hand-drawn items originally kept by the British War Office between c.1880 and 1940 and used to compile printed maps over large parts of the world. They came from a variety of sources, including military surveyors, explorers, missionaries and spies. Generous funding from Indigo Trust recently allowed us to digitise those items relating to eastern Africa.

Automated extraction of the text was carried out using the Google Vision API, which found a total of 633,451 pieces of ‘text’ on the maps. However, after the majority of erroneous results or results that were not useful had been cleaned out, the final dataset was reduced to 317,133 transcriptions. These are sorted alphabetically and displayed in an Excel spreadsheet, shown in the following screenshot:

The order in which the pieces of text were transcribed from the maps was retained in the second column of the spreadsheet so that, if the spreadsheet is re-ordered by that column, each word can also be seen in its original context – for example, the text in the screenshot below can be read from top to bottom (‘The topography has been supplied...’):

The spreadsheet enables a user to identify the image in which any piece of text appears, and links to a geographical search interface for the archive, shown below, which in turn provides links to high-res versions of the images and their catalogue records on the BL website. The combination of these resources lets users identify each piece of text and see it in context on the face of the map.

The maps are drawn in a wide variety of different hands, and the text often overlaps or is written over background features, making automated transcription tricky. Some errors do remain - for example, where individual characters have been incorrectly transcribed within words, though the words themselves should still be identifiable. In addition, not all words appearing on the maps were captured.

The resource came about after I was fortunate enough to join a cohort of colleagues from the British Library and the National Archives attending the pilot postgraduate course at Birkbeck. After speed-learning Python and SQL coding languages in the first term, I then focussed on the development of a software tool that enlists the Google Vision API to auto-transcribe text found on maps. Once made, I set it to work harvesting words found on the eastern Africa maps.

I am very grateful to BL Digital Curator Nora McGregor, who set up and coordinated the initial pilot (now launching this autumn as an Applied Data Science Postgraduate Certificate), to the Institute of Coding, who funded it, and to BL managers for allocating study time during work. This project would also not have been possible without Indigo Trust, whose generous funding to conserve, catalogue and digitise War Office maps over the last five years has made them accessible to the world online, and enabled further initiatives such as this.

A list of where to find free-to-access digitised British Library maps

Add comment

Here at the British Library we’ve been digitising our maps and making them available for over two decades now. Consequently, there’s a wealth of fantastic and inspiring free-to-view historic maps on the web. In addition to ever-increasing quantities of maps on our own platforms, our digitised maps are also hosted by other cultural institutions, organisations and individuals with whom we’ve been pleased to collaborate.

This seemed like as good a time as any to pull a load of them together and let you know about them.

So, in this first of two posts, here are a few of the places on the British Library’s site where you can find digitised maps, and upon finding them, use them escape to the ends of the earth (or the end of your street) from the comfort of your own home. Enjoy.

The Georeferencer

http://britishlibrary.georeferencer.com/start

The British Library’s Georeferencer isn’t strictly a collection of maps, since it draws its 56,000-odd maps from a variety of places (including the below sources). But you can definitely search for maps in it, for example by using this crazy map with all of the georeferenced maps located on it. Zoom in for it to make more sense, and find the area you’re interested in. 

The Shared Research Repository

The Shared Research Repository is a great place to find all sorts of British Library content, from catalogues to lists to PhD theses, to maps. This is a lively spot so keep checking in for stuff. Particular highlights are

Medieval maps and charts from the British Library and partners’ Shared Research Repository https://bl.iro.bl.uk/collection/b2393193-0749-4e81-991e-5cf394466b53

The Pelagios medieval maps project was a really excellent one which analysed and cross-referenced text contained in maps. with the added bonus of some digitised maps (thanks to funding from the A.W. Mellon Foundation).

British War Office maps of the former British East Africa  https://bl.iro.bl.uk/work/00de6f1f-a415-4b86-adb7-2a958cbdf085

Almost 600 maps, sketches and itineraries that formed the compilation material for published British War Office maps between 1870 and 1940. There is some amazingly detailed archival mapping in here. The work was generously funded by the Indigo Trust.

Online Gallery 

http://www.bl.uk/onlinegallery/onlineex/

The British Library’s Online Gallery was set up through the Library’s ‘Collect Britain’ project in the early noughties. There are thousands of maps on here, and although the Zoomify and browse facilities are no longer functioning (we’re in the process of migrating this stuff onto a new platform) there are still some great maps here, such as  

The Crace collection of maps of London

http://www.bl.uk/onlinegallery/onlineex/crace/index.html

http://www.bl.uk/onlinegallery/onlineex/crace/a/007000000000002u00056000.html?_ga=2.98418783.1764258415.1587371764-718070083.1508136830
Wenceslaus Hollar, A new map of the citties of London Westminster and ye borough of Southwarke..., London, 1675. Maps Crace Port 2.56.


One of the finest collections of historic maps of London anywhere, collected by a commissioner of London’s sewers and George IV’s interior decorator. Around 1200 maps from between around 1550-1850, digitisation generously funded in part by the London Topographical Society. Crace’s collection of London views are held by the British Museum. 

All the maps from the Online Gallery are also available (in higher resolution) alongside maps from other collections via the Old Maps Online portal (with its fun geographical search tool). https://www.oldmapsonline.org/

Turning the Pages

http://www.bl.uk/turning-the-pages/?id=223c7af8-bad6-4282-a684-17bf45bd0311&type=book

This is another older British Library resource but it has a couple of really choice atlases in it. Are there any more choice atlases than Gerhard Mercator’s hand-made Atlas of Europe of 1570 (which contains the only two surviving maps drawn by the man himself)? Or one of the volumes from the famous multi-volume Beudeker Atlas containing maps and views of Dutch stately homes from the 17th and 18th centuries.

Digitised Manuscripts

http://www.bl.uk/manuscripts/BriefDisplay.aspx

A number of maps and atlases held in the Western Manuscript collection have been digitised and found their way onto the Digitised manuscripts page. If you know what you're looking for you can search by pressmark. Or you can search by keyword (i.e. maps, plans etc.) if you're just browsing. 

Many highlights reside here, including the late 16th century Burghley-Saxton atlas (containing the first printed county maps of England and Wales in proof) at Royal MS 18.DIII http://www.bl.uk/manuscripts/FullDisplay.aspx?ref=Royal_MS_18_d_iii

Explore the British Library

The British Library's principal online catalogue does include thumbnail images for a tiny number of maps, but coverage is extremely uneven and the resolution of images is variable (to get a larger image for non commercial use, click on the map's title included in the right hand part of the details section). You may be lucky - for example if you're interested in Jacques Callot's map of the 1627 siege of Saint-Martin-de-Ré.

In a later blog I'll be listing non-British Library platforms and sites where you can find free-to-access British Library digitised maps. But in the meantime, I hope this keeps you busy.
