Djvu: Extracting ISBN numbers from a large number of books?
Hi all,

I have a large number of old math books and they're all in djvu format and filenames are somewhat messy. I'd like to import them all into Calibre so I can categorize them and fix names etc.

Is there an easy(ier) way to extract ISBN numbers other than converting them all to PDF and then running OCR on all of them? I'd really like to avoid that since that would take very long time, would produce large files, and there's still no guarantee that it would OCR all of the ISBNs properly. Option of last resort is of course to manually type all the ISBN numbers. I'd like to avoid that one of course

Thanks for any tips!

Mel
