FAQ
What is an ISBN?
An ISBN is a 10-digit or 13-digit number that identifies a book for purposes of commerce and supply chains. The last digit of the ISBN is a check digit used to detect transcription errors. This last digit is sometimes an "x".
13 digit ISBNs began to appear on January 1 2005, and all ISBN systems are required to support 13 digits by January 1, 2007.
The first number or numbers of a 10 digit ISBN identifies the country that issued the publishers prefix; this number is followed by a dash and the publisher prefix. 13-digit ISBN's start with either 978 or 979, and the 9 digits that follow correspond to the first 9 digits of a 10-digit ISBN.
The dashes (or spaces) in the ISBN occur in different places depending on the number and are meaningful, but are so frequently omitted that you can't really use the dashes for much. If you're really interested, here are the Gory Details
What is an ISBN barcode?
There are two types of isbn barcodes, the 10-digit ISBN and the 13-digit UPC with prefix 978 or 979 (a new prefix is planned). To get the 10 digit isbn from the upc, remove the 978 and the last digit (a check digit) then recompute the isbn check digit using our java class. If the 13 digit isbn starts with 979, then there is no equivalent 10-digit ISBN.
An explanation of the ISBN and UPC check digit algorithms is at Book Industry Study Group.
I want to sell my book on Amazon, how do I get an ISBN for it?
ISBN prefixes are issued to publishers by natioanl ISBN agencies. A list of the agencies is at www.isbn.org
I want to catalog my books using ISBN. How can I use ISBN to get title, author, etc?
If you're interested in cataloging a book collection check out Zarf's bookscanning project
Any barcode scanner made for the PC can be used to scan these barcodes, including the infamous CueCat ®.
We've found a nice application that helps you use ISBN to get metadata into a personal database. It's called ReaderWare.
Readerware consists of 3 separate programs for cataloging books, CD's and videos. All feature Readerware auto-catalog, the easiest way to catalog your collection. Simply scan or enter the product barcode or ISBN, Readerware does the rest. It will search the internet and automatically catalog the item for you, complete with cover art. Can be used with virtually any barcode reader.
Other features include table, tree and fish eye views, easy to use wizards, integrated backup and restore, customizable reports, import/export, standalone or client/server mode, SQL database, Palm pilot support.
Get readerware here!
Where can I get an ISBN database?
If you need an ISBN database, you have the choice of buying one or collecting free data. Because most book data is available for free, there's not a big market for ISBN databases. Nonetheless you can subscribe to books-in-print data services from Library of Congress (recommended), Muse (recommended, but expensive), Baker&Taylor; and Ingram. Most people asking this question are interested in free data, which unfortunately means they need to know about "MARC records" and "Z39.50". MARC records are how libraries add book data to their catalogs, and Z39.50 is a protocol (like http) used to request and deliver MARC records. Luckily, you don't need to know much more than that. Endnote, from ISIResearchSoft is software that can connect to libraries using Z39.50 to download book data. You can also use it with MSWord to automate the production of reference lists. You should be able to get all the ISBN data that you need with EndNote. (There's also a version for Mac)
Are there any tools for using ISBN in an XML schema?
Yes there are! xfront has a detailed schema for ISBN, as well as a pretty cool XSLT that validates the check digit. I
