Chess .pdf files

Hypocrism

I recently was given a simple E-readre that can read PDF files. I think it would be good to have a .pdf full of chess positions, no text needed, that I can just work through gradually.

 

The positions could be tactical or positional in nature.

 

Any idea where I can obtain a .pdf (or .doc) that contains an exorbitant amount of chess puzzles?
