Free Books on CD?

FosterSJC asks: "I go to St. John's College, Annapolis, home of the Great Books Program, for almost 70 years. This neoclassical method of education was developed and instituted in the late '30s by Stringfellow Barr and Scott Buchanan. We have a set syllabus that every student reads in a set order of the course of his/her four years at the college - all primary sources and in all subjects, Lab, Math, Language, Music, and Seminar. Taking a hint, partially, from the OSS CD thread a few weeks back, and this thread, I would like any and all advice about compiling a CD to give to freshman, and anyone else for that matter, containing as many of the Great Books as possible. Since most all are in the public domain (very few 20th century authors), the trick would be finding them, sorting them, organizing them, and making sure you have the highest quality translations as well (the biggest problem with the Public Domain versions of these books). Please help."
