Yeah I do grab it where I can. I just remember seeing books (and having edge cases thrown at me by users in the early days of testing) where the book only had an ASIN appearing on the Goodreads page. I guess it is more of the indie stuff where they are only publishing electronically and avoiding the ISBN costs which allegedly there is a bit of a trend on, but not being an author/publisher I confess to ignorance.
Of course even if I scraped the ASIN in that scenario (which I may do just for completeness if I can find some examples again) that still won't solve the problem if the only options for merging are ISBN or exactish title/author.
We do what we can
