MSN Money is reporting that J.K. Rowling’s edition of Harry Potter and the Philosopher’s Stone is set to be auctioned off at Sotheby’s for charity this Tuesday.  The Guardian has also posted numerous photos of the book, which contains notes and annotations from the author.

Dr Philip Errington, director of printed books and manuscripts at Sotheby’s, said: “This can undoubtedly be regarded as the definitive copy of any Harry Potter book. Not only is it a fine copy of a first edition of the first book, but the author has significantly personalised it with numerous written comments and many impressive and evocative illustrations. The personality of the author leaps from these pages and we are treated to a remarkable insight into her creative genius.”
