AbeBooks names JK Rowling Most Collectible Author

AbeBooks.com, a site for finding new and used books of all types, analyzed sales data from 2007 and created a list of the top collectible authors. JK Rowling took the top spot followed by Roderick Gordon, Brian Williams, and Stephen King: On-going demand for signed Harry Potter books means Rowling tops the index although few first editions of her debut book, Harry Potter and the Philosopher's Stone, reach the market. An autographed Harry Potter and the Deathly Hallows sold for $5,500 just after its release last July. If you're in the market for a signed Potter novel, we recommend you check out our friends at JKR's Army. They'll tell you what to look out for when shopping for a genuine JK Rowling signature.
