Pam: 
I really don't believe that Harry's possession of the book could have 
been anything except coincidence. Harry didn't purchase the required 
book for potions because he believed that he didn't recieve the 
required mark in his OWLs to continue in Snape's class. Therefore it 
was a series of complicated events: His exam results, the appointment 
of Snape as DaDa teacher, and Harry's persuasion of Slughorn that 
eventually led him to borrow the book for the year. I doubt that 
Dumbledore knew of the existence of the book, surely he had far more 
important things on his mind than a fifty year old textbook. Snape no 
doubt had gotten all the use out of the book that he could and had 
simply left it behind him when he left Hogwarts, Slughorn being the 
teacher was clearing out his classroom at the end of term and packed 
the textbook away as he no doubt did with many other books over the 
years. a simple action that teachers all over the world do at the end 
of each year. Then if a new student is in need of a book they have 
some spare...
