ISBN is a simple field/widget module. It provides simple validation for ISSN-8, ISBN-10, and ISBN-13. Javascript validation is available. Display options include raw (as inserted) and clean (dashes and spaces removed).

Drupal 7 and 8 versions

These versions are under heavy development and are not intended for production use yet.

For this version only validation through form submission is implemented. Javascript, format options and ISSN-8 validation will come soon.

Drupal 8 - Dependencies

Instead of reinventing the wheel, on Drupal 8 version of this module, both validation and format are done by an external library. The library used is Nicebooks ISBN library.
This library is already included to be download if you download ISBN module via Composer like:

composer require drupal/isbn

Drupal 6 version

Additional CCK display plugin modules could be written.
