Best source for Overdrive audiobook records when adding books?

Hi

What library or libraries do you select as sources when adding Overdrive audiobooks to librarything? Is there one library that above all others has the most records that makes it easier to add overdrive records? I usually search for the overdrive ISBN, and can often find the right record, or at least a record I can edit, but I have to try a lot of different sources, and I'm not sure if I've even chosen the right ones.

Thanks!

I just put the word "audiobook" into the search box after the title and it usually comes up with the digital file source.

>2 gypsysmom: thanks, good tip. What source do you pick?

>3 wifilibrarian: Usually just amazon.com or sometimes amazon.ca

>1 wifilibrarian: Check with your local library system, see if they've cataloged items they get from Overdrive or Hoopla Digital. I've discovered my regional system has them cataloged, so search by title and audio, then that tends to find them

>5 gilroy: Thanks for the suggestion. My local library is not available as a source in LT.
>4 gypsysmom: These are overdrive books so I'm trying to get the details for those books, including ISBNs, the details might on Amazon might not be the same.

I usually try ISBN from the details page on Overdrive, and try random libraries that I think might have more Overdrive audiobooks cataloged.
