My favourite online bookseller -- Advanced Book Exchange (http://www.abebooks.com) -- is not listed, & if appropriate I think this website should be included.
Sadly, as their books are second hand, ABE don't seem to offer an ISBN reference (each book lot has its own local ID instead). Because of this, we couldn't add it (AFAICT; IMBW and if so, someone please correct me :-)).
Of course we could add a link; it just wouldn't be ISBN-indexed, so you'd want to add a note telling the user that they'll have to search the book by title / author manually.
