Thanks for the pluggin, in general, it's great. However, I got an error:

I got a few PDF ebooks (from the same publisher) with the same ISBN extracted ....from a fax number, i.e:

Tel: +...
Fax: +... (0)1279 431059 ---> this is extracted as a ISBN number

The line of ISBN is a bit later, preceeding with ISBN ....

I wonder how the pluggin analyses the line, would it be a bug, as it should search for the keyword ISBN first (?)

Suggestion:
- Would it be possible to give an option, checking against online metadata bases with title/author/publisher... as inputs to make sure the extracted number is correct?
- When more than one ISBN are found, would it be possible to display and let the user choosing one?
- The field ISBN in Calibre can contain only one value, I wonder how to support more than one value, i.e ISBN-10, ISBN-13..
