Hi, all.
I'm wondering if there is some work done to scrap isbn out of pdf content.
I'm trying to get a big ebook collection in calibre but setting isbn by hand, one book at a time, would take more than a lifetime... so I thought of scrapping isbn from pdf content with some regex... I started to write a plugin for calibre but then thought of asking here if something like this wasn't already done or talked about before.
Anyone?
