Hi, This is to let everybody know about a campaign to try to find 10,000 digitised maps 'hidden' in 13,000 books in the set of a million images that the British Library uploaded to Flickr last year. Once they've been identified, the BL will then run the maps through its Georeferencer crowd-activity (from which we can download the full output). But first the files need to be identified on Flickr, and tagged as maps. A draft article for this week's en-wiki Signpost can be found under development here: https://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/2014-10-29/Maps_… There's also going to be an all-day tagathon session at the British Library in London to launch the effort, to which anyone who can make it is very welcome. (Even more welcome if you register first, but that's not absolutely essential), see: https://wikimedia.org.uk/wiki/Digital_maps_Halloween_tagathon,_October_2014 There is coverage of maps from all over the world, as shown by this plot of 3,000 maps on the globe, that have already been found and georeferenced: http://www.bl.uk/maps/georeferencingmap.html (Non-map images in the collection have a similar distribution). The BL Labs group are having their annual symposium meeting on Monday 3rd November. It would be fantastic, as a demonstration of the power of openness, if the lion's share of the index could have been worked through by that afternoon. Make-or-break for that target is whether people can be encouraged to help on the internet. So I would really appreciate anything anyone can do to help get the word out -- eg perhaps with mentions in the equivalents of the Signpost in other languages. I'm afraid everything is in English so far, but perhaps there is still time to do something about that. The project status page is here, https://commons.wikimedia.org/wiki/Commons:British_Library/Mechanical_Curat… which has links to all the geographical index pages, with their pink "Untagged maps" templates. These page will go live at 11:00 UTC on Friday. (Edits to them before then will probably be over-written -- though tags added on Flickr would be okay). I would be really grateful for any help anyone could give with this over the weekend, or encourage others to give. Even an hour, or half an hour to go through a block of 15 books in the index, would make a difference. So anything anyone could do between now and then to get the word out would be very very appreciated. Thanks, James.
