Released online: The 1878 India Office map collection catalogue
The India Office map catalogue of 1878, now released online for the first time on the British Library Shared Research Repository, is a valuable finding aid to one of the world's most complex and mercurial map collections.
The catalogue of manuscript and printed reports, field books, memoirs, maps, etc., of the Indian Surveys, deposited in the map room of the India office, compiled by Sir Clements Markham (1830-1916), was the first published listing of the working map archive of British East India Company, and the administration of British India from London. As the title suggests, it contains a wide variety of geographical materials, from maps to written sources and much else. Its principal geographical focus – about 70% of it - is upon the area of modern India, Pakistan, Bangladesh and Burma, but it also takes in adjacent areas, and more generally British imperial activity across the world, with the bulk of the material dating from the 19th and early 20th centuries.
In 1947 the collection, along with the rest of the India Office Records, passed into the care of the Commonwealth Office (various iterations), and in 1982 was deposited with the British Library.
As late as the 1970s the catalogue was still being used to manage the map collection; the copy we have released is the one used by archivists to record the multiple changes to the map collection that had occurred between 1878 and 1947. These changes include annotations and inserted leaves listing maps that were added to the collection after 1878, and crossings-out of material that had been removed. These latter include material relating to the Great Trigonometrical Survey which was sent to the Survey of India in 1924, and large-scale maps and plans for infrastructure projects sent to Indian provincial public works departments.
The catalogue is an indispensable aid for researchers looking to identify historical geographical sources for India and South Asia, and to order material to view onsite in the Library’s reading rooms. The ‘X’ numbers – the modern pressmarks or 'call numbers' for each unit (the material accessioned up to 1878 has the number range IOR/X/1 to IOR/X/4999), can be entered into the ‘request other items’ page of Explore the British Library under the Asia, Pacific and African Collection subset. There is also an incredibly useful alphabetical index to facilitate searching.
The catalogue is also valuable evidence of the history of the role of maps and geographical materials in the government of British India, and of imperial map archives in general. The arrangement and contents inform us of the particular mindsets and priorities of the administration (inevitably, the focus and dates of maps in the archive broadly matches Company and administration activity) and how these shifted over time.
We hope you find this a useful resource, and would be very glad to receive feedback on the sorts of ways you are making use of it in your research. You can read more about the research repository, and explore other resources available there.

George III's maps and views: 32,000 images released on Flickr Commons
In October 2020 we released 17,000 images of maps and views from George III’s Topographical Collection on the images-sharing site Flickr Commons, which seems to have kept you busy.
Well, from today, you can find an additional 32,000 images, comprising George III’s collection of atlases and albums of views, plans, diagrams, reports and surveys, produced between 1550 and 1820. These have been uploaded to Flickr with a Public Domain attribution for you to search, browse, download, reuse, study and enjoy.
What have we added?
So much! Here are some highlights:
Complete cover-to-cover digitisation of major 16th, 17th and 18th century atlases by Joan Blaeu (lots of Blaeu), Jan Janssonius (again, lots of Jansson), Abraham Ortelius (a few Ortelius atlases here), Jodocus and Henricus Hondius, John Speed, Moses Pitt, Thomas Jefferys, Mary Anne Rocque, Nicolas Sanson, Pierre du Val, Herman Moll and others. Most have never been released in their entirety anywhere online before.
Albums of topographical views by artists such as John Webber, Robert Havell, Thomas Daniell and John Clerk.
Multi-sheet maps in loose or bound format including Turgot’s plan of Paris, Morgan’s map of London, Peter Andre’s Essex, Fry & Jefferson’s Virginia, Pratt’s Ireland and Müller’s Bohemia.
Albums of 16th century prints and drawings of Roman architecture and antiquities assembled by Cassiano dal Pozzo.
Many manuscript atlases including work by Carlo Fontana, Francesco Basilicata's 1612 survey of Crete, and two Kangxi atlases of China.
How can you access them?
The first release of 17,000 images - the collection of individual maps and views, was released in one big bundle. It made sense to release this disparate group of items this way, but we appreciate that searching Flickr for specific images is not especially easy (see below, Explore, for a solution. Of course, it can be interesting to browse if you are not sure where you want to end up!).
Responding to your feedback, this second release has organised the bound atlases and volumes of prints into separate albums. The images within the albums retain the order in which they are encountered in the physical copy. The titles of the albums are made up of the constituent volume's author, title, date and shelfmark, so we hope this will make the searching experience a good one. Batching into 500 or fewer images will make downloading easier for you too.
Every image on Flickr is accompanied by metadata which includes a link to the corresponding British Library Explore catalogue record. The links are reciprocal, meaning that you can search for specific items via Explore (key tip: add ‘George III’ to your search term (free text) in order to bring up only maps and views in the K.Top). When you have found the record for the item you require (look for the record for the volume or album, rather than the record for an individual map of view within that volume, which will not contain the digital link), select ‘I Want this’ and then ‘View Digital Item’, which will take you to the relevant image(s) on Flickr.
We hope you will find everything to your liking. However, as with any large release of digital images, you may encounter the odd hiccup for which we apologise. Please get in touch with us and we’ll do our best to put it right.
Although Flickr Commons now includes pretty much everything from the Topographical Collection, there is a small handful of images which we have still to release. We're working on it!
In due course, all of this content will become available on the British Library’s own dedicated Universal Viewer, while a dataset of the entire collection will also be released on the British Library's research repository.
We are keen to hear how you are using it so please let us know and provide feedback via social media @BLMaps or by emailing us at email@example.com.
Finally, a word of thanks to our colleagues at British Library Labs for their tireless perfectionism and dedication in developing these Flickr pages.
Now off you go and explore.

The K.Top: 18,000 digitised maps and views released
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
There are links to full Marc cataloguing records on Explore the British Library. To view a digital image from the catalogue record on Explore, select 'I Want This' and then 'View Online Digital Item.'
How about georeferencing?
Glad you asked. For those of you who like a challenge, we have made all of the maps from this release available on our Georeferencer Tool. See how you get on with geolocating the maps. Some will be easier than others.
What can I do with the images?
You are free to study, enjoy, download and remix these images as you see fit. When doing so, please bear in mind any potential cultural or other sensitivities associated with them. Importantly, we’d really like to know what you are doing with the images so please let us know @BLMaps or by emailing firstname.lastname@example.org, we’d love to hear from you.
Who do we have to thank?
So very many people. Here goes:
Generous trusts and individuals including the American Trust for the British Library, Art Scholars Charitable Trust, Blue Rubicon, Viscountess Boyd Charitable Trust, Christies Education, Coles Medlock Charitable Foundation, Cornwall Heritage Trust, Cumberland and Westmorland Antiquarian and Archaeological Society, Daniel Crouch Rare Books, Dunard Fund, The Eccles Centre for American Studies, Englefield Charitable Trust, Edward and Dorothy Cadbury Trust, Hadfield Trust, John R Murray Charitable Trust, Ken Biggs Charitable Trust, Samuel H Kress Foundation, Langtree Trust, London Historians Ltd, London Topographical Society, Maunby Investment Management Ltd , PH Charitable Trust, Peck Stacpoole Foundation, Pitt Rivers Charitable Trust, Reed Foundation, Sylvia Ioannou Foundation, Swire Charitable Trust, Swinton Charitable Trust, Trefoil Trust, Turtleton Charitable Trust, Cyrus Alai, Caroline and Peter Batchelor, Michael Buehler, Tom Boyd, Richard H Brown, Claire Gapper, William B Ginsberg, Jaime Gonzalez, Martin Halusa, Jerome S Handler, Peter Holland, Tina Holland, Arthur Holzheimer, J Michael Horgan, John Leighfield, Norman Leventhal, Sri Prakash Lohia, Tom and Hilary Lynch, Lynda Partridge, Robert E Pierce, Carolyn Ritchie, David Rumsey, J T Touchton, Tony and Maureen Wheeler, Peter A Woodsford and others who wish to remain anonymous.

World Map World Cup: Group 3
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.).
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.

David Woodward, 'Medieval Mappamundi' in The History of Cartography volume one (Chicago: CHicago University Press, 1987).
2. The Martellus world map. Drawn by Henricus Martellus Germanus in Florence, around 1490 (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.)
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)
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
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
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.
Early infra-red film slide, location unknown, 1930s. BL shelfmark not yet allocated.
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.
Detail of Hind 603 beach map [Burma], 1944. BL Maps 13496.
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.’
Militärgeographische Angaben über England, 1940. BL Maps 47.g.13.
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.

The final chapter will lead this brief survey up to the present day...
