Biodiversity Heritage Library

The Biodiversity Heritage Library (BHL) is a consortium of major natural history and botanical libraries that cooperate to digitize and make freely accessible the legacy literature of biodiversity held in their collections.  Great source for older botany and zoology journal articles and books in full-text. See also their Flickr site for over 24,000 illustrations from many of their books:
