@ryan No, of course not. I'm still a student, I'm too busy to be writing books ;). I just refer to my copy of CP3 as 'mine'.
Unfortunately, my school started a whole honors track for competitive programming the year after I could take it... So no comp prog 'courses' for me. I still participated in a few algorithmic programming contests though, mainly preliminary rounds (and pre preliminary) rounds for the ICPC. Those contests do allow for printed cheat-sheets, but they can be only be about 15 pages IIRC, so no complete books.
