Goodreads Librarians Group discussion

I occasionally come across an edition with a bad ISBN. Usually it is one from an eastern bloc country, though not always. I have just been leaving them alone, but is there a way to research these and try to make corrections?

If they are actually what is on the book (and in many cases they are), there's really nothing to correct.

Thanks. That's sort of what I thought - that the system doesn't include those prefixes.
