pdf Chess Documents

I have just discovered a site called Findtoyou which contains 220 pages of pdf chess material.  Some of these are pdf’s from various websites and range from one page chess ads, excerpts by publishers, pdf booklets like mine, technical chess papers published by researchers, newsletters, etc.  In short, just about anything on the Internet that is a pdf file about chess.  You’ll have to do a lot of browsing, but who knows what you may find?!
