If you fancy access to 100,000 images and sounds courtesy of the British Library then visit Collect Britain which describes itself as “the British Library's largest digitisation project to date.” Several things are of note. It's UK National Lottery funded (New Opportunities Fund), so we, mainly the great British public, have paid for its development. But it's got '.com' in its name, so does this suggest some ultimate commercial intent?
The current site says nothing about the licensing and reuse of material for educational purposes apart from to claim “copyright the British Library Board”.
And, finally, there's not an RSS or Atom syndicated feed to be seen. That's a real pity, particularly in a British Library project.
Looks interesting though and if these few concerns above were addressed … ?
