I've been using this site for a long time, I've probably downloaded 40% of their entire catalogue. My gift to you, enjoy. (If you like the site and end up downloading a lot of titles, consider donating because copying physical books over to digital format is time consuming and tedious, and they don't charge a dime for all that free knowledge, so yea, just don't be a nigger). With that said, Mur' Chrimus'!!
