At the beginning of the Renaissance period, Gutenberg invented the printing press, thus allowing the masses, for the first time, to be able to read the Bible in their own language. It therefore opened the way for the Reformers to begin noticing discrepancies between biblical teachings and the way the church of the day was run and new churches began to spring up.
A few years ago I came across the Gutenberg project by accident but now i really like it. It provides access to all sorts of books, mostly classics, where the copyright has expired. I made a goal to read the 100 most recommended books according to the Eton press, a few of them I've read but i still have alot to go. The Brothers Karamazov, by Dostoevsky seems the likely next contender.
