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 16th century prints and drawings of Roman architecture and antiquities assembled by Cassiano dal Pozzo.
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.

While dealing with an enquiry I came across this beautifully coloured copy of Münster’s Cosmographia. This monumental publication is one of the most important works of the Reformation era and considered one of the earliest modern descriptions of the world. The first edition was published in Basel in 1544 containing twenty four double-page maps with numerous woodcut views and illustrations. The work proved to be so popular that it was followed by a further 35 complete editions and reprints in five different languages.
General Tafel Begreifend der Gantzen Undern Weldt Beschreibun from Cosmographia by S.Münster. Basel, Heinrichum Petri, 1545. BL 1297.m.6.
Sebastian Münster (1488-1552) was a true versatile scholar described as a cosmographer, geographer, linguist, historian, Hebrew scholar, theologian, mathematician, you name it! His Cosmographia is a compendium of historical and geographical knowledge compiled from information gathered as part of Münster’s personal research, international collaborations and editions of the classical authors. The work was based on up-to-date knowledge and provided the geographical and historical overview of the world, natural history, topographical features, boundaries and administrative division of the described lands, their inhabitants, flora and fauna. Divided into six books it contains a series of maps which advanced the cartographical knowledge of the time.
Neuw India, mit vilen anstossenden laendern, besunder Scythia, Parchia, Arabia, Persia etc. from Cosmographia by S.Münster. Basel, Heinrichum Petri, 1545. BL 1297.m.6.
Münster not only was the first to introduce separate maps of four known continents, he also produced regional maps many of which were the first printed depictions of a given region. His vision and surprisingly modern thinking embraced many concepts familiar to an average 21st century person. He recognised that in order for his ambitious project to be successful it required reliable information which he as much as he wanted to was unable to collate all by himself. He realised that collaboration is the key and in his correspondence invited fellow scholars to send in information about their lands. His appeal had an enthusiastic response and Münster received contributions from all over Europe, in fact Cosmographia is a product of what we would nowadays consider a crowdsourcing project.
Schlesia nach aller gelegenheit in Wässern Stetten Bergen und anstossende Lenderen. Map of Silesia published in Cosmographia also included in later editions of Münster's Geographiae Claudii Ptolemæi... BL 1297.m.6.
Not only a great scholar Münster was also a good businessmen – for example instead of commissioning new woodblocks he re-used some of the blocks (a number of which were created by artist such as Hans Holbein the Younger) from his earlier published works including his edition of Ptolemy’s Geographia (first issued in 1540). He then borrowed some of the woodblocks cut for Cosmographia and used them in his later editions of Geographia (for example the map of Silesia). Now, that’s what I call recycling!
He also recognised the potential of publishing in common languages including the rare Czech edition of Cosmographia issued in 1554 thus making knowledge more accessible by reaching wider audiences.
Depiction of German cities from Cosmographia by S. Münster. Basel, Heinrichum Petri, 1545. BL 1297.m.6.
This incredibly influential work had a huge impact on the contemporary scholars, it was used as a geographical source by famous cartographers like Mercator or Ortelius and inspired publications such as Civitates Orbis Terrarum the popular city atlas published by Braun and Hogenberg a few decades later.

When a new volcanic island emerged from the waters south of Sicily in 1831, its strategic location at the gateway to the eastern Mediterranean aroused more than a scientific interest. Geopolitical forces descended upon this tiny isle, and though its brief existence above the waves lasted just six months, four separate nations claimed it as their own.
A short volume held at the BL, ‘Views and Description of the late Volcanic Island off the coast of Sicily’ (held at BL General Reference Collection 10163.d.10. – digital version here) provides a summary of events.
Chart Shewing the Position of the New Volcanic Island of Fernandea, in Views and Description of the late Volcanic Island off the coast of Sicily, . BL General Reference Collection 10163.d.10.
The first report of volcanic activity came on 10 July from Captain Corrao, of the schooner Theresina, who approached to within two miles of...
‘a column of water rising perpendicularly from the sea, to the height of fifty or sixty feet, having a circumference of four hundred fathoms: smoke issued from it, which strongly impregnated the atmosphere of its vicinity with a sulphurous odour: dead fish were observed within the circle of agitated waters, and a violent thunder, proceeding from the same spot, added to the grandeur and the novelty of the scene!’
The Volcanic Island of Fernandea, in Views and Description of the late Volcanic Island off the coast of Sicily, . BL General Reference Collection 10163.d.10.
Commander C.H. Swinburne of the Royal Navy arrived in the area a few days later –
‘I saw flashes of brilliant light mingled with the smoke, which was still distinctly visible by the light of the moon. In a few minutes, the whole column became black, and larger; almost immediately afterwards several successive eruptions of fire rose up among the smoke... At five am, when the smoke had for a moment cleared away at the base, I saw a small hillock of dark colour a few feet above the sea.’
Views of the New Volcanic Island of Fernandea, in Views and Description of the late Volcanic Island off the coast of Sicily, . BL General Reference Collection 10163.d.10.
The opportunity to claim the island was too good to miss. On 3 August, in a lull between eruptions, Royal Navy Captain Senhouse landed there to plant the British flag, and named it Graham Island after Sir James Graham, First Lord of the Admiralty. This act prompted representatives from Sicily, ‘highly excited by this achievement within sight of their shores’, to embark from the nearby port of Sciacca and plant their own flag, that of Ferdinand II, King of the Two Sicilies. They named the island Ferdinandea, shortened to Fernandea on the chart above.
Over the following weeks French and Spanish claims were added to the list, but all such attempts to gain geopolitical advantage proved futile. Eruptions ceased from the middle of August, and by the end of the year the island, whose maximum extent was a mere two miles in diameter and 160 feet high, had slipped back beneath the waves. From that point it appeared on British charts as Graham’s Shoal, a bank lying eight meters beneath the surface.
More recently, in 2002, volcanic activity was recorded there again, and it was thought the island might re-emerge. In a bid to avoid being beaten to the mark a second time, Italian divers planted their national flag on the seamount beneath the surface. However, activity soon ceased and the shoal remained where it was.
Modern-day volcanologists agree that the descriptions of volcanic activity at Graham Island conform to what is known as ‘surtseyan’ activity – named after a more recent undersea eruption, which produced the island of Surtsey (from Surtr, the Norse God of Fire) off the southern coast of Iceland.
This eruption is thought to have begun in early November 1963 at a depth of 130 meters, but by 15 November a crater had become visible above the waves. The event caught the imagination of the televisual age – a number of clips on YouTube show footage made at the time.

The BL holds a map of the island made by the National Survey of Iceland using aerial photographs taken in October 1964 (BL Maps X.12169.). Eruptions continued until 1967, by which time the island no longer conformed to the map, but the sheet provides a fascinating snapshot of the island’s formation a year after it first emerged.

A block of text in Icelandic and English provides a summary of the different phases of eruption, and the map itself gives significant detail of the island’s contours and constituents.

Unlike Graham Island, and most others of their type, this example has persisted above the waves. It is estimated that roughly a quarter of the island has now been lost to erosion, and its maximum height has reduced to 155 meters, but it is likely to survive above the sea for another hundred years.
In this case there were no diplomatic squabbles over ownership, and its affiliation to Iceland is undisputed. But its persistence has made it especially valuable to science - 69 species of plant have been found there, 12 species of birds, and numerous other animals, including earthworms and slugs. In recognition of its value as a centre for the study of biocolonisation UNESCO declared the island a World Heritage Site in 2008.

Mapmaking is a highly exacting profession, as the scrutiny of current pandemic mapping demonstrates. Yet the fascinating thing about mapmaking is that everybody is capable of creating a map, and throughout history 'amateur' mapmakers have brought something new to the table.
Christopher Packe (1686-1749) was a local physician based in the area of Canterbury in Kent, who during his 'many otherwise tedious' medical journeys around the area was struck by the similarities between the landscape, features and processes of the natural world and those of the human body. Most notably, and unsurprising for a physician, the synergy between hydrology (specifically streams and rivers) and the flow of blood through the arteries and capillaries. As I mentioned in a previous post, there’s a strong history of thought positioning the human body as a microcosm of the universe. Packe's 1743 Philosophico-Chorographicall chart of East Kent is the Gunther von Hagens of maps.
Looking closely we can see the tremendous series of lines of thousands of tiny watercourses connecting to streams and thence to rivers, flowing out into the sea. So many of them, in fact, that we might be looking at a map of the English Fenland.
That's not all that Packe's map shows. Shading and spot heights communicate the relative heights above sea-level which Packe measured using a barometer. This has led to the map being described as the world's first geomorphological map. And finally there is the series of concentric circles demarking the map's co-ordinate system. These emanate from Canterbury and the cathedral, from which Packe used a theodolite to survey the county and form his aesthetic and philosophical vision (see Michael Charlsworth for an in-depth study).
Packe wrote a treatise in support of his work, and even produced a 'specimen' sample of the larger map six years earlier, a sort of taster which was presented to the Royal Society. A copy of the specimen is in the Topographical Collection of George III, published 'at his own expense.' Indeed, Packe put so much into his map that it is possible to imagine life in it, the culmination of a creative act. Something, if you will forgive the further analogy, created from the heart.

In October we released 18,000 digital images of early maps and views from the Topographical Collection of George III. View the collection on Flickr Commons, and access images via the maps and views' catalogue records on Explore. Here's my choice of five compelling maps from the collection.
1. Plan of Manila, 1739.
This is the only recorded example of this 1739 edition of the 1717 town plan of Manila in the Philippines. Manila was, and is, a key international centre of trade, and the map was actually produced in the town (in a tiny vignette we can see a copy being presented by the Spanish governor of the Philippines to King Philip V of Spain). There’s probably no better image of a bustling commercial site, proof that a town is not just about its architecture and layout, but its people and processes too. This map has additional resonance, because Manila was besieged and looted by the British in 1762, and annotations in the map’s bottom right refer to aspects of the battle. Could it be George himself annotating the map according to reports he had received of the battle?
D. Antonio Fernandez de Roxas, TOPOGRAPHIA DE LA CIUDAD DE MANILA : CAPITAL de las yslas Philipinas
Manila: Hipoloto Ximenez, [around 1739].
2. Map and survey of Plymouth Harbour, 1780
This is the map that reminds me most of the strong links between mathematics and art in maps. It’s a large and serious military drawing, officially commissioned and with an accompanying report, of a key strategic naval installation and site of British maritime strength and power. It was drawn up as part of the earliest mapping activities for what would become the Ordnance Survey a few years later, enacted in response to the threat of invasion from Napoleonic France. So why is it so stunningly and mesmerizingly beautiful? It’s a question that should infuriate everyone who sees maps purely as cold communicators of facts and 'data.'
Matthew Dixon, Colonel, surveyor.
‘A General Plan with a Project for the Defence of the Arsenals of Plymouth, / By Lieut: Colonel Dixon Chief Engineer of the Plymouth Division. Revised and corrected by Geo. Beck Jan. 1780.’
3. Aquatint view of Kingston-upon-Thames, 1813
Thomas Horner, Kingston upon Thames. 1813
Is it a map or is it a view? What is that ominous large shadow looming in, Holbein-like, from stage left? Who cares! This is an intriguing and brilliantly composed aquatint print showing a collection of views of picturesque Kingston-upon-Thames. From above, in profile, from a distance away, it’s a multi-faceted image that invites us to dissolve our perception of the differences between vistas and to see them as a combined and rounded description of a place. Cartographic cubism! As Horner himself wrote, ‘…the whole, blended into one design by a picturesque fore-ground, forms a faithful view of the parish.’ It’s a joyous visual experience, with a few intrigues and little jokes (note the bungling surveyor- stonemasons in the foreground) thrown in for good measure.
4. India, 1619
This is a portentous map - the earliest British printed map of part of India. It marks the beginning of British cartographic involvement in India that would reach new levels of science-led imperial control through mapping by 1900. The Roe-Baffin map was produced following the earliest English trade mission to the Mughal empire. It has a stellar cast: Sir Thomas Roe, the diplomat who headed up the embassy. William Baffin, the navigator who went on to attempt to locate the North West Passage (Baffin Island is named after him). Reynold Elstrack, one of the earliest native English engravers.
The map was one of very few English-produced maps to provide a model for later Dutch atlas maps by Blaeu, Janssonius and others. English mapmakers were more often the copycats. The engraving of a Mughal seal has been expertly assessed by the British Library’s Dr Annabel Gallop.

[London] : Are to be Sold in Pauls Church yarde. by Thomas Sterne Globemaker., 
5. The United States of America, 1782
This is a map with a story and a reminder of the power – and paranoia – that can be associated with maps. John Mitchell’s map of ‘the dominions of North America’ is a tremendous cartographic achievement in its level of description of this vast area. Yes, standing on the shoulders of earlier maps, but adding a vast quantity of descriptive notes and even including naming Native American nations (who were nevertheless ignored in what followed).
On another level, this late edition of the map is a piece of history, being the copy used by the British delegation at the 1782 Treaty of Paris where the terms of the peace following Britain’s defeat at the hands of the United States were established. The map has been marked up in red to show the lines of the new border the British would be happy with. But at the conference they realised that they didn’t have to cede quite as much as they had drawn. The map suggests that Upper Canada (much of modern-day Ontario) was also available to the USA. So later the British government ordered the British Museum to lock the map away so that nobody, particularly no inquisitive Americans, might see it and demand any more.
It was hidden from view until the early 20th century.

A guest post by Chantelle Richardson, Librarian of the National Library of Jamaica and former Chevening British Library Fellow
Throughout my year at the British Library, I was privy to seeing some amazing resources. One of my projects focused on Non-book Bibliographic materials from Latin America and the Caribbean before 1950. Compiling the list of materials for this project allowed me to view various items related to the Caribbean region. However, my interest piqued when I would see items related to Jamaica, especially maps.
My fascination with maps began when I started working in the Special collections branch at the National Library of Jamaica. Historical maps provide a vivid depiction of what the past looked like. They can be useful for a multiplicity of information needs. Land allocation is one aspect that is of particular interest. Maps can be used to see how communities were structured then and how they are now.
I found that one of the best ways to browse the cartographic holdings at the BL was by using the printed catalogues available in the Maps Reading Room. Though most items can be found on Explore the BL (the online catalogue) I found the printed catalogues useful in helping me to navigate the vast collections. It is therefore good to know that a complete set of metadata relating to one of the Library’s treasure collections, the King’s Topographical Collection (K.Top.) will soon be made available on the BL Shared Research Repository – an ideal tool for browsing which is similar to how you would navigate the printed catalogues.
Interestingly, I found that the BL has maps and other special collection items such as prints like those present in the NLJ collections. The K.Top. Collection is one of the best examples of this.
James Robertson, MAP of the County Of Cornwall, In The Island Of Jamaica. London, 1804. Maps K.Top.123.52.b.11.
The K.Top. Collection features many maps from the Caribbean in general. There are several maps related to Jamaica directly and indirectly. The names of cartographers like James Robertson, Edward Slaney and Nicolaes Visscher popped out as all have holdings in the NLJ collections.
Nicolaes Visscher. Insulae Americanae in Oceano Septentrionali ac Regiones Adiacentes. Amsterdam, 1775. Maps K. Top.123.5.
The coloured Jamaica maps in the K.Top. Collection are particularly interesting. Aside from being appealing to the eye, they give information on the parishes, towns, and counties. Researchers wanting to analyze the division of land in Jamaica from when there were 22 parishes to its 14 now can use the coloured maps as reference.
Another interesting thing about the K.Top. Collection is that it not only has maps related to Jamaica but prints as well. Prints such as The Maroons in Ambush on the Dromilly Estate in the Parish of Trelawney, Jamaica are a good source for researchers who are interested in indigenous groups and resistance.
J. Mérigot, The MAROONS in AMBUSH on the DROMILLY ESTATE in the PARISH of TRELAWNEY, JAMAICA. London, Robert Cribb, 1801. Maps K.Top.123.59.
There are also prints by lithographers like George Robertson and Louis Belanger. These prints are an added benefit of the K.Top. Collection as they help to contextualize what was happening in some of the places identified on the maps. For example, a MAP of the COUNTY of Middlesex, IN THE ISLAND of JAMAICA has an explanation section which I found somewhat depicted in one of Robertson prints A VIEW IN THE ISLAND OF JAMAICA.
James Simpson, MAP of the COUNTY of Middlessex, IN THE ISLAND of JAMAICA. London, 1763. Maps K.Top.123.51.c.2.tab.
Researchers wanting to find a visual representation of rivers, harbours, estates, and aspects of plantation life during the 18th century may find these items useful.
J.B. Harley stated that he saw cartographical mapping of the British Empire as a language of power and not protest. The same could be said of some of the Jamaican maps. To ignore the imperial association of how the maps became a part of the K.Top. Collection would not be an objective stance. Like many of the other Caribbean maps featured in the collection, most of the Jamaican maps were acquired throughout the 16th and 19th century when Britain ruled much of the Caribbean. These maps can be used in research that explores themes like the role of early maps in Britain’s imperialist past, area studies, postcolonial studies, land ownership and geomapping.
With the COVID-19 global pandemic remote access is becoming a major focus for libraries worldwide. Researchers who use both BL and NLJ resources have increased in the demand for digital materials. It was good to see that all the maps relating to Jamaica and the Caribbean from the K.Top. Collection have been digitized and are now openly available worldwide through the BL Explore and Flickr platform.
In the coming months, I plan to input links from the K.Top. maps collection into the NLJ maps catalogue so users will have access to the digitized copies of these resources from our holdings. Having used these resources, I recommend it to all users for academic as well as personal research.

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.
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

UK hydrographic charts published by the British Admiralty in the early twentieth century are notable for the high density of information compressed within their two dimensions, and for the harmonious blend of registers and visual perspectives they incorporate in the pursuit of clarity. Whilst documenting local visual navigation techniques handed down over the centuries, charts from this period also feature networks of lights, beacons and buoys more recently installed around the coastlines of the British Isles.
This example, first surveyed and published through the Hydrographic Office in 1847, shows the bays of Long Island and Baltimore in West Cork, Ireland with information updated to 1909.
Detail of Admiralty Chart 2129, Long Island and Baltimore Bays, Ireland, 1909. BL Maps SEC.1.(2129.)
As the seabed rises towards land, the approaching navigator is assisted by depth soundings, and abbreviations that tell the composition of the seabed at each point – sand, shells, gravel... The original measurements were taken with a sounding line marked along its length in fathom intervals, that was dropped over the side of the survey vessel. The lead plummet at its end was covered with sticky pitch or tallow that brought up a sample of the sea floor beneath.
Some of these data points cluster around and almost interfere with the map title. Navigators would use these measurements to inform the plotting of their routes and, by dropping their own sounding lines, would attempt to pinpoint their location.
Along the bottom edge of the sheet, a sketch testifies to a tradition of visual navigation techniques that have persisted even through the introduction of electronic aids later in the century. ‘View A’ provides a perspective in silhouette of the entrance to Skull Harbour, and demonstrates how Cosheen Crag in the foreground should be lined up with Barnacleeve Gap on the horizon in order to avoid rocks at Castle Ground on the way in. This horizontal view nestles on the page between the scale bar and a compass rose, while further soundings caught in-between call for a vertical viewpoint.
The correct angle of approach to Skull Harbour is also marked with a line across the chart. A number of other sightlines bisect the chart at various points, guiding seafarers past areas of danger.
More recent networks of buoys, beacons and lights also appear - in an update to earlier editions a light has been added at the western entrance to Baltimore Harbour. The chart indicates a wide arc facing southwards and out to sea from which the light appears white, and the crossover point upon entering the harbour from which the same light shows red.
For a distance inland, just enough of the topography - relief, landmarks, buildings and communications - is provided that might be of use to a vessel and her crew, before the detail gradually rubs to a blank on the chart.
The visual attraction of these sheets lay in the skill of the production draughtsmen whose finished drawings were transferred to copperplate for printing. From the late 1960s a programme of modernisation was introduced to update Admiralty Charts with metric units, simplified lettering and colour washes – a palette of blues for different water depths, and buff for the land – a style that persists to this day.
