If you don't mind reading off a screen, instead of turning pages, this is a very cheap way to discover old books. A Kindle or Sony Reader device is best, but laptops/tablets/smartphones will do (they will cause eye strain though).
There is no cost because these books are in the public domain (in certain countries). The copyright on each work has expired (usually: out of print for 50 years or 50 years since author died) and kind volunteers type or scan the whole thing in, and make it available for free. The laws are slightly different in each country, so really you should check each book to see if you are permitted, before downloading.
