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.
3D virtual globes
We just did this, and we hope you like it. 3D virtual models of 10 of our historic globes from the 17th - 19th centuries with thanks to our Digitisation Services and digitisation company Cyreal. Another 20 will be added over the coming months.
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.
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.
20th century maps
Here are round a hundred maps from articles produced as part of our 'Mapping the twentieth century: drawing the line' exhibition.
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
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
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.
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.

During the current pandemic, the next best thing to heading outdoors is (of course) to lose yourself in the printed landscapes of maps instead. In our London flat last weekend, I couldn’t help reaching for my Ordnance Survey Explorer sheets of the English Lakes and tracing the routes of Easter walks in years gone by.
Although busy depicting roundabouts and service stations, road maps and atlases also give us armchair explorers a flavour of the landscapes, the countries and the times we move through in our mind’s eye.
This example from the United States comes from a time when the American highway map was at its peak, when the automobile was an icon of progress, and state departments and commercial oil companies handed out road maps in their millions, free of charge.

While useful to many, these maps were also the vehicles for carefully chosen images and text promoting industry, nature, social progress and Christian values. A Motorist’s Prayer on this sheet begins, ‘Our heavenly Father, we ask this day a particular blessing as we take the wheel of our car...’

A similar agenda is found on the other side of the Iron Curtain, where a Soviet regional map from the same year focussed on places and monuments of revolutionary history, industrial mines (asbestos, brown coal, gypsum...), pine forests and swan nesting sites.

Industrial prowess is emphasised again in the strong design on the cover of this regional atlas.

But unlike in Britain or America, the Soviet general public had no large scale Ordnance Survey or US Geological Survey maps to turn to for raw topographical detail. These were restricted to the military. Even generalised maps were deliberately distorted during the 1970s to make them harder to use for navigational and targeting purposes, should they fall into the wrong hands.
After the break-up of the Soviet Union, restrictions on sophisticated military mapping were relaxed, and elements of larger scale maps made their way into practical road atlases, amongst other products, for the general public. The evolution of these maps from military specification to a hybrid form more closely resembling the typical road map can be traced over the following years.

In the road atlas on the right new colouring distinguishes road types and routes, and makes them more prominent while rivers fade away, and symbols are added to indicate petrol stations, medical facilities, museums and places of interest.

Precise bridge dimensions and maximum loads have been removed, though contours and direction of river flow remain, and the close mesh of the military grid has been replaced by a broad system of squares that correlates with the place name index at the back.

At last the landscape was revealed, and civilians could take to the open road better equipped.
And who knows, perhaps even now fingers are tracing imaginary routes from armchairs throughout Russia...

'Atlas: a world of maps in the British Library' is a different sort of atlas to, say, the Times world atlas or the AA motoring atlas, because you would never use it to find your way from A to B or peruse potential venues for your next holiday.
This is largely because the maps in it are mostly pretty old and do not all conform to our modern idea of accuracy.
The most common question people ask me about an old map is “is it accurate?” On such occasions I would like to be able to sound one of those alarms like in the BBC quiz show QI. But to be polite I tend to answer that “it is as accurate as it was possible to be” or “it is accurate for its time.”
Angelino Dulcert (atrib.), [A portolan chart of the Mediterranean Sea (detail)], c. 1339. Add.MS 25691.
Accuracy is relative and incredibly subjective. For example, 14th century 'portolan' sea charts look freakishly accurate because although they are really old we can recognise familiar coastlines in them. Yet if we look more closely, we see that each cape, bay and inlet is exaggerated and distorted in size because – guess what? – the map had to be legible for its user.
William Roy, [A map showing the Trossachs, part of the fair copy of the military survey of Scotland], 1747-55. Maps CC.5.a.441., sheet 15 (part).
William Roy’s map of Scotland of 1747-55 looks very accurate, and indeed is regarded by some as one of the first modern maps and a precursor to the Ordnance Survey, but it hasn’t been geodetically measured, and the sweeping hill forms sit more in the realms of landscape art.
Anon. [Map showing the position of the Indian tribes to the north-west of South Carolina, copied from a painting on deer-skin by an Indian chief, and presented to Sir Francis Nicholson], c. 1719. Add. MS 4723.
The 1719 Native American map of Carolina is woefully inaccurate by these standards, but more accurate than anything else in its description of the complex interrelations between tribes (shown as circles) and European colonial powers (squares).
Few maps produced before the 19th century will pass muster if judged by contemporary standards of mathematical accuracy. But if we judge old maps by contemporary standards we can miss the genuinely insightful perspectives they provide on the periods and people they concerned.
They can also help to shine a light back onto ourselves. For who would have thought that a modern and ‘accurate’ map such as a motoring atlas would exaggerate and distort features such as roads in order for users to read them more clearly?
'Atlas: a world of maps from the British Library' is out now.

Above: early Canadian aerial photography from the Colonial Copyright Collection, from Wikimedia Commons.
This summer, to mark Canada's 150th anniversary celebrations, the British Library will be displaying a selection of photographs from its Colonial Copyright Photograph Collection under the title, 'Canada Through the Lens'. The photographs contained in the collection were received from Canada between 1895 and 1924 under legal deposit regulations and in 2012 the Library began to digitise this collection in collaboration with Wikimedia Commons and the Eccles Centre for American Studies.
Back in 2012 I was the curator for Canadian collections and so I thought that this year I would merge my old work with my new responsibilities by making a map of the material digitised in 2012. The Picturing Canada Project, as this work was called, was a successful attempt to release a collection online under Public Domain licensing but browsing material in the list-based structure of Wikimedia Commons can be laborious. Given most people who access the collection want to find photographs of places that interest them (for personal or research reasons) a map seemed like a good entry point and so we've been tinkering around with using the collection metadata to display an interactive map. The first results can be seen here:
The map has been built by inputting metadata relating to the collection (largely derived from original copyright records and work done by P. B. O'Neill of Dalhousie University in the 1980s) into a spreadsheet and then adding to this the best geographical coordinate data we could find. This data was then uploaded to Google Fusion Tables, which can produce a map as one of its software tools. When it comes to the geo-data sometimes we have been lucky and been able to pin a location accurately. However, in many cases we have roughly developed a location by tracing place names in the photograph title, while in others we have had to pin the location of the photographer's studio or make a best guess as to an appropriate location. As a result, the geographical data you see above is a good start but very much a work in progress.
Above: 'Buying miner's licenses in Victoria for the Klondike gold-rush', J. W. Jones (1898). An example of a photograph with place specific data in the title. Image from Wikimedia Commons.
Each point on the map corresponds to a photographic record and clicking on the icon will provide users with metadata on the image as well as a link to the image on Wikimedia Commons. In some instances there is no link as there is more work to do uploading a few files to Commons or removing metadata for images that were not digitised (for an explanation as to why, see the Picturing Canada project page). The colouration attributed to the icons is an attempt to visually depict when photographs were produced and each colour means the following:
- Yellow, 1895 - 1899
- Green, 1900 - 1909
- Red, 1910 - 1919
- Blue, 1920 - 23 (end of active period of legislation)
'Canada Through the Lens' will open at the British Library on May 26th so we have plenty of time to polish the map and its content ahead of the main release. As part of this, if any of you spot problems or have suggestions for refinements feel free to email me at: philip[dot]hatfield[at]bl[dot]uk.

In this exclusive guest post, map historian John Davies introduces one of the most enigmatic of 20th century map genres.
'The story of Soviet military mapping is the story of a massive secret project, spanning the fifty years of the Cold War period – from the 1940s to the 1990s – and involving thousands of people. It’s the story of the world’s largest mapping endeavour and, arguably, the world’s most intriguing maps.
The story of this amazing enterprise has never been told in full in print and the maps themselves have rarely been publicly displayed. One of them, however, the city plan of Brighton on England’s south coast is on show in Maps and the 20th Century: Drawing the Line.
The full extent of the project will probably never be known, but it is safe to say that almost the entire land surface of the globe was captured on topographic maps at scales of 1:1 million and 1:500,000. Huge areas of the Americas, Europe and Asia were mapped at 1:200,000 and 1:100,000, whilst maps at scale of 1:50,000 (the same as the familiar Ordnance Survey Landrangers) cover much of Britain and continental Europe. On top of that, the vast territory of USSR itself was mapped at 1:25,000 (the scale of Ordnance Survey Explorer maps) and much even at 1:10,000.
The topographic maps have sheet boundaries corresponding to lines of latitude and longitude. This means they are non-rectangular, the two sides narrowing towards the top in the northern hemisphere. The sheets are non-overlapping and are identified by a reference number that uniquely identifies the global location and scale of every sheet.
It works like this: each 1:1 million map is a quadrangle which covers an area of the globe four degrees of latitude deep and six degrees of longitude wide. The latitudinal bands are alphabetic, starting with A at the equator and increasing as you head north; the longitudinal zones are numbered 1 to 60. The Greenwich meridian (longitude 0) defines the boundary between zone 30 and 31; London, at latitude 51, lies in band M (the 13th band, spanning latitudes 48 to 52). London west of Greenwich, therefore lies in quadrangle M-30 and east of Greenwich in M-31.
International Map of the World nomenclature adopted by Soviet Union, with lettered bands of 4° latitude and numbered zones of 6° longitude
This convention, known as IMW – the International Map of the World – nomenclature was devised originally by Albrecht Penck at the end of the 19th century and was adopted in 1913 for a proposed international cooperative mapping project. Although that project fizzled out, the USSR made use of the same convention and did succeed in mapping the whole world by the mid-20th century.
As you zoom in on a 1:1 million sheet, you get 4 sheets at the larger scale of 1:500,000 (numbered 1-4); 36 sheets at scale 1:200,000 in a 6 by 6 grid (numbered 01-36), and 144 sheets at 1:100,000, in a 12 by 12 grid, (001-144). Zooming further in, for each of these you get 4 sheets at 1:50,000 (numbered 1-4).
Part of sheet M-31, scale 1:1 million, compiled 1969, printed 1975, showing the non-rectangular edges, aligned to lines of latitude and longitude.
Part of sheet M-31-1, scale 1:500,000, compiled 1978, printed 1985.
Part of sheet M-31-01, scale 1:200,000, compiled 1982, printed 1986. Road distances in km are overprinted in purple.
The reverse side of the 1:200,000 series sheets has a comprehensive essay describing the physical, social, economic and industrial importance of the locality, together with a geological sketch map.
Part of sheet M-31-013, scale 1:100,000, compiled 1976, printed 1982. Note the M25 under construction.
Part of sheet M-31-013-3, scale 1:50,000, compiled 1974, printed 1981. This is the SW quarter of M-31-013. Note the A2 road is also labelled E107 (upper left), a European road number that did not appear on British maps.
The projection used is the Gauss-Krüger (G-K) projection, based on a regular system of Universal Transverse Mercator projections that each cover a zone 6 degrees wide, with central meridians (axial lines of longitude) at 3 degree intervals. The advantage of this is that it simplifies the depiction of the globe as a flat surface for relatively small areas and allows the use of a rectangular grid within each zone. The grid provides accurate geographic co-ordinates to facilitate precise artillery targeting.
The security classification depended on the map scale; small-scale maps (1:1 million and 1:500,000) were unclassified; 1:200,000 maps were classified as ‘For Official Use’, as were 1:100,000 and 1:50,000 maps of non-USSR territory. Maps of USSR territory larger than 1:200,000 were classified ‘Secret’.
Even more remarkable than the topographic maps are the city plans. These are known to exist for about two thousand cities worldwide, and there may have been many more. City plans are to a large scale, either 1:25,000 (two-and-a-half inches to the mile) or 1:10,000 (about six inches to the mile), and show an altogether much greater level of detail, including street names and listings of factories and their products, public buildings and transport facilities – even relatively unimportant (certainly non-military) objects such as bus stations and post offices. They are classified ‘Secret’.
City plans are rectangular, being based on G-K projection with a central meridian near to the city. The sheets themselves vary in size, but are typically about 1,000 mm by 800 mm, and may be oriented as portrait or landscape layout to suit the terrain to be covered. Many cities require several sheets (in Britain, typically two or four; in USA, Los Angeles requires 12 sheets and New York 8). Unlike the topographic maps, in which the coverage is continuous and non-overlapping, city plans are individual, specific sheets, centred on a particular city; in some cases, such as the conurbation of West Yorkshire, the plans of several cities overlap.
About 100 British and Irish cities are known to have been mapped in this way, several of them more than once. Halifax, Luton, Cambridge and Cardiff are just some of the places for which maps of the 1970s and again of the 1980s exist. The later editions are entirely new productions, rather than revisions of the originals.
The coverage of British cities includes not only the major industrial and commercial centres and important seaports and naval bases, but relatively rural and less strategically significant places such as Gainsborough and Dunfermline (although Rosyth Royal Naval dockyard is not far from Dunfermline, it is not included in the map coverage).
The information depicted on city plans is derived from a wide variety of sources and includes detail not normally seen on local street atlases. For example, the 1990 Brighton 1:10,000 plan seen in Maps and the 20th Century: Drawing the Line shows signals alongside the railway line, annotates the shoreline as having a mean tidal range of 4 metres, differentiates the vegetation types in parks and open spaces and identifies the ownership of facilities such as motor repair depots.
City plans have a street index, a descriptive essay and a list of ‘important objects’. numbered and colour-coded on the map – purple for administrative buildings. black for industrial and green for items of military importance.
Part of 1:25,000 plan of London (sheet 1 of 4, compiled 1980, printed 1985) showing colour-code and numbered ‘important objects’. These are listed in the index as:
- State Archives [actually Public Records Office]
- Foreign Office
- Ministry of Defence
- Government offices
- Courts of Justice
- Police – Scotland Yard
- General Post Office
- Radio station BBC
- Residence of the Queen and Prime Minister [actually Her Majesty’s Theatre]
- Greater London Council
- University of London
- HQ of the US Navy in Europe [actually American Embassy]
- HQ General Staff
Note also the depiction of tube stations (symbol M), arrows showing direction of flow of the Thames and direction of tides, Kingsway tunnel and symbols indicating lawns in Hyde Park. The river name is in upper case lettering, denoting that the river is navigable. None of this information appears on contemporary Ordnance Survey maps]
Part of 1:10,000 plan of Thurrock (compiled 1974, printed 1977) showing Tilbury docks and the Dartford tunnel
All the maps described above, the topographic maps and the city plans, were produced by VTU, the Military Topographic Directorate of the General Staff of the Soviet Army and are headed ‘General Staff’. They carry in the bottom right-hand corner a print code, defining the map type, when it was printed and at which of the twelve print factories spread across the USSR.
How and Why
Two obvious questions spring to mind when looking at these maps. How did they do it? And why did they do it?
Neither has a simple answer.
Copying from Ordnance Survey maps, for example, is an obvious possibility. However, the wealth of information shown far exceeds what could be derived from these. Analysis of the information shown on Soviet maps and plans proves that the compilers and cartographers had access to a huge range of published maps and guides. They include commercial street atlases, geological maps, transport maps and timetables, trade directories, tourist guides Admiralty charts and many other sources. Although these would have been freely available in Western cities, it is surprising to see just how wide the net was cast and intriguing to consider the process by which material was gathered and transmitted to USSR.
Even more surprisingly, the sources include items which had been published many years previously, resulting, for example, in the maps depicting ferries alongside the bridges that superseded them and long-disused railway lines being shown as operational.
After the launch of Zenit satellites in 1962, aerial imagery became a significant component in the data sources and can be seen in many cases where new roads and housing estates, for example, which had not yet appeared on Ordnance Survey maps, are shown on Soviet maps. Often these have the street names omitted, indicating that the cartographer had only the aerial image to hand and not the latest street directory.
As to why so much time, effort and money was expended on this gigantic project for over fifty years, we can only speculate. The concentration on depicting civil rather than military information suggests that these were intended not as invasion maps, but as necessary tools to manage and control the economic and industrial activity of Western cities after their eventual peaceful conversion to communism. But who can say?
Wasn’t the West doing the same thing during the Cold War?
Of course, mapping the territory of a potential enemy was nothing new and not restricted to the Soviet Union. But during the Cold War, the West, generally, was far more selective about where they mapped and what they showed. Whereas the Soviet Union produced huge numbers of city plans, each of which shows minute detail of all aspects of a city (regardless of military significance), the West tended to focus on places of particular interest – and included on their maps only what was relevant to the purpose.

John Davies is editor of Sheetlines, the journal of Charles Close Society for the Study of Ordnance Survey Maps (www.CharlesCloseSociety.org) and is co-author with Dr Alex Kent of The Red Atlas: How the Soviet Union Secretly Mapped the World, to be published by University of Chicago Press in September 2017 (http://redatlasbook.com/)

One of the key exhibits in Maps & the 20th Century: Drawing the Line - in fact one of the key maps of the 20th century - is a world map of 1942 by MacDonald Gill. Called 'The "Time and Tide" map of the Atlantic Charter', the map was published (in Time and Tide magazine) to commemorate the signing of a wartime agreement between Britain and the United States of America in August 1941.
MacDonald Gill, The "Time and Tide" Map of the Atlantic Charter.London, 1942. British Library Maps 950.(211.).
The treaty, which was agreed by Winston Churchill and Franklin D Roosevelt on a warship moored off Newfoundland, set out their aspirations for a post-war peace, including self-determination and global economic freedom. This symbol of friendly co-operation between Britain and the USA was designed as a threat to the Axis powers, for the USA was not at that time at war with them. The 'special relationship' dates from here.
The map brilliantly illustrates a world, unified under the sun and with images of trade and prosperity. It is a post-war Utopian vision that has been made possible by the treaty.
MacDonald Gill, ' The Atlantic Charter', 1942. Private collection.
MacDonald Gill was a highly successful British illustrator who produced work for customers as varied as London Transport, the Tea Market Expansion Board, Cable & Wireless Ltd., and St. Andrew's church, Sunderland.
He was a particularly skillful draftsman, as visitors to Drawing the Line can see from today when the original pen sketch for the Atlantic Charter replaces the printed version on display. As Gill experts Caroline Walker and Andrew Johnston have noted, Gill seems to have applied ink directly to the paper without any need for preparatory sketches or guide lines, and there isn't a smear of Tippex in sight.
Even more amazingly, the drawing has original signatures of Churchill and Roosevelt pasted onto it.
Maps & the 20th Century: Drawing the Line is open until 1 March.

I love panoramas and this one inspired my love of the Alps and mountain mapping.
Heinrich Berann, [Jungfraubahn mountain railroad, Switzerland], 1939. British Library Maps 1060.(4.).
Panoramas form a fascinating niche collection within the 4.5 million maps in the British Library’s collections. They have a long history and my second favourite is the 1851 fabric view of London produced for the Great Exhibition with south at the top and the original ‘Crystal Palace’ laid out in Hyde Park.
Changing mapping technologies have influenced the panorama and its uses in war, discovery and peaceful pursuits especially winter sports.

The British Library's current exhibition Maps & the 20th Century: Drawing the Line showcases the finest exponent of the late 20th century, Heinrich Berann (1915-1999) and his panorama of the Atlantic sea-bed. An Austrian, Berann began with his Grossglockner Hochalpenstraße of 1934 and his final panoramas of U.S. ski areas came out in the mid 1980s.
My favourite is one I discovered while sipping a non-alcoholic beverage in a street café in Interlaken and is a paper beer tray mat with an image of Berann's Bernese Oberland panorama (top image). Under the glass, this utterly stunning piece of art showed the whole area in perfect, sunny weather, a wispy cloud over the Jungfrau, each railway, road and mountain in perfect detail. It made me want to explore more… once the rain clouds had dispersed of course. And it was there to be got wet, scrunched up and thrown in the bin… how!
This map made me realise there was more to maps than an my trusty Ordnance Survey sheet of Hexham, no matter how good they were, and I wanted to discover more about cartography in all its facets. Berann is no longer with us but his panoramas still inspire cartographers and art lovers alike.

Maps & the 20th Century: Drawing the Line is now open

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.
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.
