This little plugin validates ISBN-10s and converts them to the newer standard, ISBN-13. Some sites that pull metadata are not great at matching the two versions, so ISBN-13 may get more and more current information.
The plugin will handle multiple selections, and will skip blank or invalid ISBNs.
This is my first plugin, and my first real venture with Python as well, so I welcome the feedback.
Special Notes:
- Requires Calibre v0.8.57 or later.
Installation Steps:- Download the attached zip file and install the plugin/add to context menu or toolbar/restart Calibre as described in the Introduction to plugins thread.
