>>Why would Snape leave the HBP book in his old potions class?  If I
were to have made a bunch of helpfull notes in my book I would have it
in my private library.  The only thing I can think of is that he left
it there knowing that Harry wanted to take the class, but wouldn't be
prepared for it.  I'm not saying that Snape was trying to help Harry.
 Maybe he was trying to get him expelled.  Snape knew that the book
had dark spells in it that weren't explained.  I'm betting that Snape
also knew that Harry's curriosity would get the best of him.

CathyD now:
Well, I've been asking myself the same question.  LIke you I would never have let the book out of my own hands/office.  All I can think of is that he's obviously made another copy of the book - maybe one with clearer, easier to read notes - for himself.  Even thinking that, I can't believe he left the other one just laying around where any student could gain access to it.   Snape had pretty much given up on getting Harry expelled by GOF (in fact, did he threaten expulsion in GOF?  He threatened veritaserum once and told him he would *pay* but he never said expel).  Snape only gave Harry detention for nearly murdering Malfoy.  That was grounds for expulsion if anything was. Was Snape trying to help Harry?  I don't know, but Harry finally learned Potions from Snape, didn't he?  (I think you can tell this is a big plot-hole to me...I just can't get around it.  I will *not* believe in a Puppetmaster!Dumbledore...as Kreacher said "won't won't won't"...and that DD fixed all this so Harry would end up with Snape's old potions textbook.)
