This is a simple extension that will extract all ISBN from any web page. Extracts all 10 or 13 digit ISBNs (even if separated by spaces or -). If you want to make the list comma separated or anything like that I recommend http://sortmylist.com/ **Update Version 1.1 ** Updated ISBN matching pattern. ISBN scraping now is a bit cleaner Updated to latest Google APIs Fixed problem of not extracting after switching tabs
