Another big list of where to find British Library maps online

Add comment

In a previous blog I described the best free-to-access digitised British Library maps available on the Library’s own site. But there are more. Lots more!

Where we’ve worked with other institutions, organisations and individuals on digitisation, we’ve been pleased for those institutions to host the resulting content on their own sites. Often, the maps we’ve provided form a subset of a wider collection drawn from a range of other sources. So it isn’t just about the spirit of collaboration, but the enormous research benefits to be drawn from a broader and more integrated picture.

In the fullness of time you can expect to see this content also hosted on the BL's Universal Viewer. For now, here are some of the riches and where to find them.

Wikimedia Commons Collections

https://commons.wikimedia.org/wiki/Category:Collections_of_the_British_Library

There’s a ton of British Library content on Wikimedia Commons which is great because of the open access nature of the site and its clear usage terms. Maps are included in a range of categories, including the Off the Map videogame competition and Images Online (the British Library’s commercial imaging site). But the main category, labelled maps collections, contains 28,000 images. Three main ones are

Ordnance Surveyor drawings - https://commons.wikimedia.org/wiki/Category:Ordnance_Survey_Drawings

Robert Dawson, [Ordnance Surveyor Drawing of part of Berkshire], 1809. Maps OSD 106 

 

These 321 maps are some of the earliest works by the Ordnance Survey of Great Britain, which was formally established in 1791 to map southern England in response to the threat of invasion from France. The phrase ‘scope-creep’ is something of an understatement when applied to the OS, whose work continues to the present day. These large ‘fair drawings’ are the maps produced by the earliest Ordnance Surveyors of parts of England and Wales from the 1790s to the 1840s, and it’s from these that the one inch to the mile ‘Old Series’ printed maps were derived. The maps were received in 1958. For close, local work, there’s really nothing better than these for the period.

Goad fire insurance maps - https://commons.wikimedia.org/wiki/Category:Goad_fire_insurance_maps_from_the_British_Library

Charles C. Goad Ltd., Insurance plan of Sunderland, sheet 7, 1894. Maps 145.b.12.(8.).

Charles Goad’s maps are incredible windows into Britain’s urban past – stupidly detailed late-19th and early 20th century maps of various towns produced in order to assist the calculating of fire insurance risk. To do this, the maps included not only tell us the shapes and forms of buildings, but what they were made of, and who was using them and for what. Over 2,500 here for you to savour. Goad mapped other world cities including a large number of Canadian towns.  

War Office Archive - https://commons.wikimedia.org/wiki/Category:War_Office_Archive_%E2%80%93_East_Africa

Thanks to the Indigo Trust, over 1800 East Africa maps and materials from the wider WOA have been digitised and placed here for your study and enjoyment. They’re also georeferenced. Hurrah!

Maps of Qatar and the Middle East

https://www.qdl.qa/en/search/site/?f%255B0%255D=document_source%3Aarchive_source&f%5B0%5D=source_content_type%3AMap

Through the Library’s partnership with the Qatar National Library, over 1300 maps of the area, drawn mostly from the India Office Records, have been catalogued and uploaded onto their digital library portal.

American Revolutionary War Maps

In collaboration with the Norman Leventhal Map and Education Center at Boston Public Library, 377 maps of North America and the West Indies from the American Revolutionary War Era were digitised and placed on the Center’s educational site. Ten other partners including the Library of Congress also contributed material. The British Library's contribution includes maps from the King’s Topographical Collection and Royal United Services Institute, which itself contains maps from the collection of Jeffery Amherst (1717-1797), commander-in-chief of British forces during the Seven Years’ War.

Japanese produced historic maps

https://mapwarper.h-gis.jp/maps/tag?id=british+library

We digitised all of our pre-1900 maps of Japanese origin thanks to a wonderful collaboration with Ritsumeikan University, Kyoto. And what a collection – over 300 maps drawn from the Map Collection, the Western Manuscripts Collection, and Asian and African Studies Collection. Some of these maps arrived from earlier private libraries including the Engelbert Kaempfer and Philipp Franz von Siebold Collections. Some of them are very big indeed. You can access these maps through the Ritsumeikan University MapWarper portal.

Maps of Singapore and South East Asia

https://eresources.nlb.gov.sg/printheritage/browse/Charts_Maps_British_Library.aspx

The five-year project between the British Library and National Library of Singapore, generously funded by William and Judith Bollinger, enabled us to digitise and upload 300 maps onto the NLB Singapore’s web portal. These cover Singapore and its wider geographical context. 

Flickr maps

https://www.flickr.com/photos/britishlibrary/albums

In 2013 the British Library Labs’ Mechanical Curator project placed 1 million British Library images onto Flickr. They are images drawn from books digitised as part of the Microsoft Books project, and include an enormous wodge of maps (‘wodge’ in this sense meaning tens of thousands of maps). See this individual album containing over 25,000 maps https://www.flickr.com/photos/britishlibrary/albums/72157648036792880

These are the maps which are currently being Georeferenceed via the Library's Georeferencer tool http://britishlibrary.georeferencer.com/start

The Roy map of Scotland

https://maps.nls.uk/roy/

Roy composite
William Roy [A section of the military survey of Scotland], 1747-1755. Maps CC.5.a.441. 

And finally, just one map, but a very large and important one. This is the fair copy of General William Roy’s (1726-1790) map of Scotland produced between 1747 and 1755. The map is a landmark in British mapping for applying military surveying methods to a very large area, and is regarded as the precursor to the Ordnance Survey. It’s also highly regarded artistically, since it includes the hand of celebrated watercolour artist Paul Sandby (1731-1809). The map is part of the Kings Topographical Collection, having formed part of the collection of the Duke of Cumberland.

We’re delighted for the National Library of Scotland to host this map on their website, given its signal national importance. And they do a very good job of it too, with a superb interface and numerous layers, including a 3D one.

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.

900 or so images, many of them maps from the King’s Topographical Collection, illustrating a series of new and repurposed articles on the subject of illustrating place. The project was generously funded by the Paul Mellon Centre for Studies in British Art, The Finnis Scott Foundation, Marc Fitch Fund and Coles-Medlock Foundation.

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

Jacques Callot, OBSIDIO ARCIS SAMMARTINIANÆ. Paris, c.1631. Maps C.49.e.75

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.

Hooked on Georeferencing

Add comment

Georeference NY

Above: a map of Manhattan from the US subset.

A funny thing happened last week as I noticed that the Georeferencer project's current phase had stalled around the 32% mark. Having checked on the project progress bar for a few days I decided we had lost momentum on the project, perhaps due to it being the summer holidays, personal commitments, a frustration with some of the content, or any other number of other reasons. Deciding I could not encourage more use without 'practicing what you preach' and getting stuck into the current cache of maps, I sat down in my breaks - for the first time in too long - to work through a chunk of the project using the lists of maps 'to be georeferenced' held on Wikimedia Commons.

After working my way through a number of maps I noticed two things. First off, progress on the Georeferencer project has not stalled, instead the counter on the front page has mysteriously stopped working (if you go there now you will still see it needs fixing). Instead, if you go to the 'Participants' tab you will see a different picture, one that suggests that, far from stalling, the project is actually charging along. At the time of writing 24,508 maps have been georeferenced, around 42% of what is currently in the system. The second thing I noticed was that I was hooked. Again.

Pandora voyage

Above: the route of the Pandora, from the Arctic subset.

Yes, despite the fact that there is no emergency or need to inspire more work on the system I'm still finding spare time to do 'just one more', the cartographic equivalent of computer gaming's 'One More Turn' syndrome. Now that I'm hooked I thought I would share some maps I georeferenced that worked out particularly well; the New York one lines up very pleasingly (grid systems make georeferencing much easier) while the map of the voyage of the Pandora satisfies my enthusiasm for Arctic maps, but, as usual, I have enjoyed working on every map I've done in this batch. I should probably back off a little now - not least as I have to sit down and write some talks around my new book - but I suspect I'll be dropping back in for 'Just One More Map' on a regular basis.

Thanks go out, as always, to our volunteers who are working through this large volume of material. We are making great progress here at the Library adding the data produced to catalogue records for the sheet charts, atlases and printed books that contain these maps and each newly georeferenced map means more useful data can be added to the catalogue. For those of you working on the project, don't forget about our lists of maps to be georeferenced over at Wiki Commons, they really do make the project more enjoyable - as I suggested in a previous post. For anyone reading this who wants to get involved in the project for the first time you can find out how here.

Less of a Random Mapper: a new feature for Georeferencer

Add comment

Tropical Australia

Above: a map of tropical Australia, from the 'Australia and New Zealand' subset.

Those of you who have used the British Library's Georeferencer in the past will know that it has an interesting quirk; you don't get to choose the map you are working on. This was added to the design for good reason, to make sure even the difficult maps in the selection get worked on, but it also has disadvantages. You see, the random pool is quite small, around 30, and doesn't change unless a map is georeferenced; this means that, with a challenging set of maps like those currently in the program, the same unpopular maps can just keep circling around until someone bites the bullet and gets that map pinned down. All of which means, it can become a bit of a drag for even the most devoted Georeferencers.

Map of Kendale (Kendal)

Above: 'A map of Kendale' from the 'North West' subset.

Thankfully, some of our wonderful volunteers have worked on creating a solution to this problem. A new page on Wiki Commons now lists all the maps requiring georeferencing by their rough location (i.e. a country) or some other subject marker (such as the map being about 'anthropology'). Next to each subject line is a link saying 'to georef', click on this and your route to selecting material to work on in the Georeferencer begins. All you need do from here is  click on a map on the Flickr page you have been directed to and on the map’s page click the ‘View this map on the BL Georeferencer service’ link. You are now at the Georeferencer interface for this map, simply log in and continue the georeferencing process as normal.

Georeferencer subject page (Flickr)

Above: a view of the 'Anthropology and Ethnology' subset page.

Using this process you can continue to find, select and georeference maps of your choosing, working your way through an entire list or flitting from one subject to the next. The choice is yours. Since I last wrote we've progressed up to 27% of the maps from the current batch georeferenced, that's a whopping 13,434 maps! Plus, all this data is now being ingested into the Library's catalogues and should be available on the public interface soon.

As I always say when I close these posts, if you've not started working on the georeferencer yet please do come and have a go. Now is a better time than ever to start.

Money for old charts: printing maps in the nineteenth century

Add comment

History of Kent

Above: A map from Henry Francis Abell's, History of Kent, as overlaid by the Georeferencer.

With 2016 well underway it is a great pleasure to see work on the 50,000 maps held in the Georeferencer continuing apace. It looks like our volunteers were very busy over Christmas and the numbers processed have jumped, heading well beyond the 20% mark with a total of 11,644 now georeferenced. I must confess I had intended to provide a festive post to showcase some of our more wintry maps but in the excitement of the run up to Christmas completely forgot to post it. And so the Georeferencer’s yuletide treats have to pass unmarked – until next year.

For today’s post I’ve been paying more attention to the UK maps being worked with in the Georeferencer. These make up a significant proportion of the content being processed and the UK is the densest area of pinned maps both for this element of the project and the Georeferencer work as a whole. Having recently moved to Kent I decided to have a dig around the maps pinned here, hoping to find some interesting items. This turned out to be a success but not in the way you would necessarily expect.

The above map comes from Henry Francis Abell’s, History of Kent, with original sketches and maps which, as you can see, makes a significant amount of of the ‘new maps and illustrations’ contained in the work. The only issue is that Abell had previously published a children’s history of Kent which contained exactly the same map and now the Georeferencer hosts them both side by side, highlighting Abell’s recycling of old map plates. Aside from being an insight into a slightly disingenuous writer or publisher’s practice of selling books these two maps open a door on a much wider practice of nineteenth century illustration production.

The BL 1 Million stream of images, from which this map is pulled, have allowed digital humanities researchers to analyse the content in various ways, comparing and contrasting images with each other. One of these researchers, Mario Klingemann, (recently awarded a BL Labs prize for his work) noted the prevalence of reproducing and slightly amending previously published illustrations in order to drive down the cost of production for publishers. In short, what Abell is up to with his maps was a relatively well established nineteenth century practice, especially where cheaper books were concerned.

Railroad GB

Above: Map of the Railroads of England designed for Edward Churton's, The Rail-Road Book.

One other item worth drawing attention to is this railroad map of Great Britain, which I stumbled across while looking for interesting maps of Lancashire. It reminded me that one of our volunteers, Susan Major, has recently published a work on railroad history - and you won’t be surprised to hear that Susan georeferenced this particular map for the Library. That’s all for this particular georeferencer update, there is more to come about the project and work of our volunteers in March. In the meantime, if you are new to the Georeferencer and would like to get involved, you can find out more here.

Putting yourself on the (old) map

Add comment

Most of you know the British Library and a dedicated group of volunteers have, for the last few years, been plugging away at georeferencing maps from across the Library’s collections. The most recent, and rather large, set of maps has been carved out of the cache of Library images held on Flickr and now our volunteers are working their way through over 50,000 maps in need of georeferencing. Thanks to the work of our dedicated georeferencers things are progressing well, with over 9,000 maps referenced so far but for those of you interested in getting involved there are still plenty of opportunities for you to do so.

Above: the geographical spread of the maps georeferenced so far.

As you can see above, the georeferencing done so far has already dealt with maps from an impressively wide geographical area. In fact, there are now so many maps available I'm going through them and picking out some that strike me as particularly interesting. The below map of the expedition of Baron Adolf Eric Nordenskiӧld into the interior of Greenland is from a publication about his 1883 trek to understand more about the continent, it's also one of my favorites from the current georeferenced batch. The map almost made it into the Library’s recent Lines in the Ice exhibition as Nordenskiӧld encountered what he thought was a new mineral, Kryokonite, but which turned out to be coal dust deposited by snow. In short, Nordenskiӧld found some of the earliest evidence of the global circulation of pollutants – he just didn’t know it yet.

Nordenskiold in Greenland

Above: map of Baron Adolf Eric Nordenskiӧld’s 1883 Greenland expedition. See in Georeferencer.

For completely different reasons I’m also very keen on the two following maps, depicting late nineteenth century Niagara Falls (both sides) and Melbourne at a similar time. It’s not so much the content of the original maps as their situation on the contemporary Google Map which interests me here as both now form small parts of sprawling urbanised areas. Niagara Falls has not developed in the same manner as Melbourne, which grew explosively in the late twentieth century, but both maps and their background say a lot about twentieth century urban development.

Niagara Falls

Above: Niagara Falls, Canada and U. S. A., published 1886. See in Georeferencer.

Melbourne

Above: Melbourne, Australia, published 1888. See in Georeferencer.

It is these sorts of historical nuggets and contemporary juxtapositions which make the BL Georeferencer so interesting and if this whets your appetite to get involved I have good news, there are still plenty of maps left to work with. You can find out more about the process of signing up and working with the material here. Another gem to come out of the work of our volunteers’ work is the availability of these maps through the wonderful Old Maps Online. This has been available through a web browser for some time but it now comes to you in a mobile phone app too.                                    

There is more information about the app and its uses via this press release from the Old Maps Online team and it is well worth a read. For the purpose of this blog the most pertinent thing to point out is that the maps you reference from the current cache of material will also be available, in the palm of your hand, through this app. The bonus feature of the Old Maps Online app is that you can now find maps about where you are, wherever you are, so long as you have your phone, a signal and (especially if you are outside of your home country) a suitable mobile data package.

This means that if you go for a walk, say, on the Downs of Kent you can open the app and see georeferenced material about your location originating from the British Library, and other institutions who have taken part in the project. All this while stood in a field, a bog, a forest or a town. Have a go, it really is great fun.

A Rare View of the Siege of Boston (1775-1776)

Add comment

The British Library is pleased to have a number of of maps and views currently on display in a special exhibition at the Norman B. Leventhal Map Center at Boston Public Library. These maps, which come from the King's Topographical and RUSI collections, were digitised and catalogued thanks to a project involving the Leventhal Map Center and generous private sponsors. The exhibition is entitled 'We Are One: Mapping America’s Road from Revolution to Independence,' and we are delighted to host this guest blog post about the display by Allison Lange. 

In late April 1775, twenty-five-year-old British Lieutenant Richard Williams left Europe for Boston to take part in the American war. The battles of Lexington and Concord earlier that month had prompted British troops to retreat to the city, which was soon surrounded by American soldiers. Williams landed in Boston in June, and—despite the circumstances—he was glad to be there. He declared in his diary, “the Land was a pleasing object after six weeks of absence from it.”

Williams’s duties were tied to the land. As a cartographer and artist, he mapped the area for military and political leaders to study. The British Library’s map collection includes several pieces of his work that offer unique, beautiful views of life during the siege.

The day after his arrival, Williams took stock of Boston. He went to Beacon Hill to view the rebellious colonists surrounding the peninsula. “Boston is large & well built, tho’ not a regular laid out town,” he concluded. Williams thought the area had seen better days “before the present unhappy affairs” when “it was livly [sic] and flurishing [sic].”

Add_ms_15535_5[Richard Williams] (active 1750-1776), 'A Plan of Boston and its Environs Shewing the True Situation of His Majesty’s Troops and Also Those of the Rebels, Likewise All the Forts, Redoubts and Entrenchments Erected by Both Armies.' 1775. Manuscript, pen and ink and watercolour. British Library Add.MS. 15535.5.  Publicdomain

Williams used his view from Beacon Hill for his maps and sketches. He likely drew the Plan of Boston and its Environs Shewing the True Situation of His Majesty’s Troops, which is part of the British Library’s map collection, from this spot. The map depicts the positions of the British and American troops in October 1775. Fortifications were colored yellow for the rebels and green for the British. Camps, like the one on the Boston Common, are red.

Richard Williams (active 1750-1776), 'A View of the Country Round Boston, Taken from Beacon Hill…Shewing the Lines, Redoubts, & Different Encampments of the Rebels Also Those of His Majesty’s Troops under the Command of His Excellency Lieut. General Gage, Governor of Massachuset’s Bay.' 1775. Manuscript, ink and watercolour. British Library Maps K.Top 120.38.  Publicdomain

In addition to this map, Williams captured the landscape with watercolors like A View of the Country Round Boston, Taken from Beacon Hill. He sketched Boston’s churches and homes and documented the British camps that had transformed the city into a military base. At the bottom of the scene, Williams included a key to identify fortifications like Castle Williams and the “Redoubts of the Rebels.”

British military and political leaders commissioned maps like these to gain a better sense of the Revolutionary War. Williams drew his Plan of Boston and sent it to London, where it was printed less than two weeks before the British evacuated the city on March 17, 1776. He also sent his watercolor view, one in a series, to London. This piece eventually made its way into the British Library’s King George III’s Topographical Collection.

After evacuating Boston and sailing for Nova Scotia, Williams became ill and abruptly stopped writing in his diary. He returned to England, where he died on April 30, 1776. Although he died young, the unique views he left behind offer valuable insights into life during the siege.

For the first time, the British Library has loaned these items for display in the city that Williams captured on paper. Williams’ work is featured in the Norman B. Leventhal Map Center’s exhibition at the Boston Public Library. The exhibition, We Are One: Mapping America’s Road from Revolution to Independence, uses maps to explore the events that led thirteen colonies to forge a new nation. We Are One demonstrates that maps, from Williams’s plan to early maps of the new nation, were central to the revolutionary process. The exhibition features maps as well as prints, paintings, and objects from the Leventhal Map Center’s own collection and those of twenty partners, including the Library of Congress, William L. Clements Library, and John Carter Brown Library. Explore geo-referenced maps from the exhibition here.

The exhibition will be on display at the Boston Public Library through November 29, 2015. We Are One then travels to Colonial Williamsburg from February 2016 through January 2017 and to the New-York Historical Society from November 2017 through March 2018.

The Leventhal Map Center also hosts the NEH-funded American Revolution Portal database. Researchers can access maps from the American Antiquarian Society, British Library, Library of Congress, and other institutions in one search. Users can download images for research and classroom use.

We have 50,000 maps online that we ask you - the public - to identify the geographical location of.   The BL Georeferencer release is now live at

Stockholm1
A plan of the city of Stockholm” published in 1802, overlaid on current Google mapping

Using the BL Georeferencer online application, you will be presented with a historic map from a 19th century book; by finding the location on a modern map or imagery alongside, the old map is “georeferenced”, and can be overlaid and interacted with in your browser (as above).

This is our largest release of maps yet, and will be a formidable task to complete, so any amount of help you can offer us will be gratefully received!
