The British Library has announced that it will be adding its collections of public domain digital images to Flickr. The first collection set is Highlights from the Mechanical Curator, which includes images from over 65,000 books from the 17th, 18th and 19th centuries. Other collections are also scheduled to be added.
From the Flickr website:
The images currently have very little metadata associated with them (though they do link back to the original digitised books), and we want to invite you to discover the content in the library’s photostream and add your knowledge to it by commenting and adding meaningful tags to the images to help develop the more than 1 million photos currently available on Flickr. The library will be leveraging our Flickr API in order to build crowdsourcing activities to improve the image descriptions over time and gain a greater understanding of what resides within.
