I've started a new category at Deep Thoughts. Whenever I come across a resources that can be used to support Atheism, I will post a brief description and link. I found The complete work of Charles Darwin while researching a book I am reading about fundamentalism. I appears to be a comprehensive and searchable resource.
This site currently contains more than 50,000 searchable text pages and 40,000 images of both publications and handwritten manuscripts. There is also the most comprehensive Darwin bibliography ever published and the largest manuscript catalogue ever assembled. More than 150 ancillary texts are also included, ranging from secondary reference works to contemporary reviews, obituaries, published descriptions of Darwin's Beagle specimens and important related works for understanding Darwin's context.
