The Internet Sacred Text Archive is the largest freely available archive of full-text books about religion, mythology, folklore and the esoteric on the Internet. The site is dedicated to religious tolerance and scholarship.
In addition to sacred texts, the site gathers commentaries, myths, essays, Greek and Roman classics and histories. (The Confucian canon is also available in English and Chinese on the site.)
In order to keep the Web site free, they sell the contents of the site in a searchable CD or DVD format.
