Maps on the British Library's Online Gallery: update

The British Library’s ‘Online Gallery’ was first created in 2004, and over the years a number of galleries containing thousands of maps have been added to it, from the earliest Ordnance Survey maps to Tudor mapping. Each map has its own page with a full description and cataloguing information, a downloadable image, and a larger – though not downloadable - ‘Zoomify’ image.

However, at the end of last year, Adobe ceased to support Flash player and Zoomify became inoperable. For anyone who likes to zoom into a map (about 100% of people who use maps), this is an issue. This is what we’ve done to solve the problem. Firstly, we’ve removed the Zoomify links from the map pages in order to avoid confusion (you can still download a -full-size’ though under 1 MB image for your own use).

For the more heavily used galleries, we’re happy to say that the maps are available – and downloadable - from Wikimedia Commons.

For the Ordnance Surveyor Drawings, the still-active Zoomify link will redirect you straight to the same map on Wikimedia.

The Goad fire insurance maps are all there also.

Only 2,500 George III Topographical Collection maps and views were on the Online Gallery, but you can now enjoy 18,000 of them on Flickr, with even more on the way (you can link through to these images via our catalogue Explore the British Library).

And don’t forget that all of the Online Gallery maps are also available on our Georeferencer (have a go at Georeferencing a few).

Have a look at this and this blog post to discover where else you can discover British Library maps online for free.

For the other galleries such as the Crace Collection of maps of London, we are working to find a way of getting the larger images to you (you can still download smaller images from the existing pages). In due course also, these maps will all make their way onto the Library’s Universal Viewer.

Thanks again for using the Library’s online map resources. And if you get the chance, do drop us a message about the interesting things you’re doing with them.
