Less of a Random Mapper: a new feature for Georeferencer
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.
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.

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.
