Removing the title and author and searching
only by ISBN often works. Not so much on pre-ISBN books though.
I've also had luck with the Goodreads plugin and the identifier for the specific edition, though it's possible the new site designs messed it up. Find the URL for it (you need to do this manually; note the 'editions' is kinda hidden on the page) and use the paste button on Ids column.
Example:
https://www.goodreads.com/book/show/76620 (main one)
https://www.goodreads.com/book/show/901687 (the specific edition I have)
