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!

I had the same problem, i like my books in pdf since it is compatible with many OS/Devices and can be compressed , for some reason the metadata is lost after conversion to pdf . I use free software btw for that.
