small thing in COS: Possibility

Ever since I saw the interview with Rowling where she says 
she "nearly gave it all away" in Chamber of Secrets, I've been 
turning it over and over in my mind and wondering what little detail 
I missed that might give away the whole story.

Here's a thought (and it's way out in left field, so it's okay if 
you disagree): Petrified Hermione is clutching a small piece of 
paper telling about the Basalisk.  However, given Hermione's respect 
for books, it seems so unlikely to me that she would _tear_ a page 
out of a book - probably a LIBRARY book at that.  

Is it possible that someone left that information for her, or gave 
it to her?  If so, it of course leads to several questions: Who gave 
it to her? How did they get the information about the chamber?  And 
why did she not say someone gave her the info or left it for her to 
find?
