ISBN-UPC-EAN Lookups

If you are involved with the selection or ordering process, then you are very likely to be familiar with searching for items by the International Standard Book Number, or ISBN.  The newer, 13-digit ISBN is actually based on the European Article Number, or EAN, which makes books consistent with most international trade goods.  The EAN was developed as an expansion of the common Universal Product Code, or UPC.

Enough theory?  How about web sites that offer lookup services that can help you find booksellers, prices, and even reviews and summaries of the books you wish to acquire?

• BookFinder – This site returns a large number of booksellers (many, many used booksellers!), although it seems odd that it doesn’t display the book’s title.
• CheckUPC.com – A good summary, and a variety of printable bar codes make this a decent site for book information.
• ISBN.nu – This is one I have used for years, and is still the one I turn to when our primary vendors don’t have a book in stock.
• ISBNdb.com – With summaries, subjects, similar items, and physical details, this site is a great resource for information about books.
• OCLC’s xISBN service – This service returns a list of related ISBNs, other editions of the book whose ISBN you append to their base URL ( http://xisbn.worldcat.org/webservices/xid/isbn/ ), in XML format.  It isn’t pretty, but when you need it, it is very helpful.
• ThingISBN – Similar to xISBN, LibraryThing provides a service where you append your ISBN to the end of their base URL ( http://www.librarything.com/api/thingISBN/ ) and get a list of related ISBNs in XML format.
• UPC Database – This site returns a large number of booksellers of the group; it also lets you know that the UPC is associated with that fictional country that so many people enjoy visiting:  Bookland.
• Wikipedia’s Book Sources – If you want a service that can give you dozens (and dozens!) of places where you can “Find This Book”, then you need to try this one.
