International Standard Book Number (ISBN) is a universal, unique and numerical identifier for books. Length of ISBN was 10 digits until 31 December 2006. Since 01 January 2007, the length of ISBN has been 13 digits.
Although now ISBNs are issued in the 13-digit form, you might still want to convert an ISBN-13 into an ISBN-10. You may have a legacy software that works but only with ISBN-10 format. Your bibliographic database might still require an ISBN-10 to be entered. These are only some of the reasons why ISBN-10 might still be useful for people.
This online tool takes an ISBN-13 as input and apply an algorithm on it to instantly come up with the equivalent ISBN-10 format. You can use this tool for free. You can also find the reverse tool here.
An ISBN barcode is a graphical representation of the ISBN number. Such a barcode can be easily scanned with the help of an ISBN barcode scanner. An ISBN barcode is the standard implementation of the European Article Number-13 (EAN-13) barcode.
This ISBN Barcode Generator tool is completely free, you don't have to pay anything to use it! This tool allows you to download the resulting barcodes in image formats (like JPG, PNG, GIF) as well as vector formats (EPS, AI, PDF). Here you can customize your ISBN barcode with a chosen code color, background color, size and resolution.
The objective of ISBN is to uniquely identify a book or edition of a book, or monographic publications including braille books, microform, electronic publications, audiobooks, educational/instructional videos/DVDs and software.
Publishers of books apply for and purchase ISBN from an affiliate of the International ISBN Agency. Each country has one or more such affiliate agencies.
