Friday Free Stuff: The Biodiversity Heritage Library
20 January 2012
A consortium of natural history and botanical libraries have digitised 14 collections, or almost 100,000 books, on biodiversity and related topics. The books are available as pdfs, jpgs, or OCR'd text, and records can be downloaded into BibTex or Endnote. Works are either in the public domain or given a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 license.
One of its collections is particularly cool: the Charles Darwin collection currently has 330 of the titles from Darwin's own library and where possible has scanned his own copy so you can see the marks and notes he made in the margins.
