Abe Lookup (available to registered users only)
The Abe Lookup will do a first pass search through AbeBooks.com to attempt to find the book based on the title and the author. The search is not foolproof, it requires a match between the title and the author, but will generally provide a good starting point. If the seller has misspelled the name, for example, the book will not be on the returned list. Before making a selection, it is advisable to do an advance search.
