I can't find any information on rate limiting with the Google Books API. I'm interested in doing ~300K total ISBN queries to retrieve lists of book categories, and I want to throttle my requests to stay under their limit. I have a developer API key, but not OAuth. Does anyone know what the rate limits are for the Google Books API, or at least have a ballpark?

Perhaps off topic but would it be possible to run a similar script to retrieve book thumbnail images? I only have 5,000 books but a script to do this would be great!

If you're just looking for thumbnails, I would highly recommend using the book ISBNs to grab data from the Goodreads API. They have a pretty high percentage of books with usable thumbnails, and they provide images in a variety of sizes.

Is there a Google Books API node to retrieve all book categories?

According to this post,

Around 100k/day is not a problem.
You can also request more quota, if you need it, as follows:
- Go to the API Console (https://code.google.com/apis/console)
- Select "Quotas" on the left navigation pane.
- Click on the "Request more..." link and submit the form.
"Your quota request should be processed within a few business days at most. Basically we want to hear from our developers so we know what type of traffic they are sending, so we can add resources to accommodate them as necessary. But from what you describe, perhaps 100K/day, should not be a problem."
