Digitised books and journals free online - mainly (but not exclusively) older material
Biodiversity Heritage Library – full texts of books and journals, well catalogued and easily navigable, but no full text searching
Internet Archive – full text searching of digitised books and journals, including most/all of the material in the Biodiversity Heritage Library (although navigation is not as good as BHL)
Google Books - full text searching of digitised books and journals, but cataloguing/navigation tends to be disorganised
