The Darwin Correspondence Project has announced that it is opening an online database of approximately 5,000 letters exchanged by Charles Darwin, including letters from his college days, his HMS Beagle voyage, and letters exchanged around the publication of The Origin of Species. The database is part of an ongoing project and website developed by Cambridge University's Centre for Applied Research in Educational Technologies (CARET). The project homepage features a daily quote from the letters with a link to the full text and links to related materials, such as a page on Darwin and religion. The DCP began in 1974 as an effort to compile Darwin's letters and is being accelerated in advance of the Darwin Bicentenary to be celebrated at Cambridge in 2009, which will be the 200th anniversary of Charles Darwin's birth and the 150th anniversary the of publication of The Origin of Species.
