Where librarians and the internet meet: internet searching, Web 2.0 resources, search engines and their development. These are my personal views and not those of CILIP or any other organisation I may be associated with.
The Macaulay Library is the world's largest and oldest scientific archive of biodiversity audio and video. It's mainly birdsong, and can be searched with the usual search box, or by category. It's an excellent collection, based on my very limited understanding of the subject area and if you've an interest in the great outdoors, it's worth a quick delve into.
