I have it going, but my collection is so large it stops after page 399. My library is 43,492 so 1740 pages, but Amazon only shows 400 pages. I've downloaded the first 400 pages of A-Z, and last of A-Z. A-Z authors first 400 and last 400. I'll do most recent and oldest purchases. I'm afraid I'll be missing some books. Any suggestions? I plan on doing individual categories for collections, but have 1,461 not in a collections so I'm afraid I'll be missing some books. Is there a way for it to continue?

Reverse the sort sequence and it starts back with page 1 now being the first one you bought. Copy the link from the browser page then paste it into the @Move line and save. Go to the browser page and refresh. I had 2 machines going from both directions.

And I thought I had a large library! You definitely have me beat. I was able to get all mine through the method you used above. I never could get the script to run past page 400.

Just wanted to say "Thank you" @lfhbento.
The script worked great (when Amazon didn't screw up). The change for device in the list was also much appreciated.

Worked perfectly, thanks!

Thank you so much @lfhbento. Ran it from the browser console and it worked brilliantly.

@lfhbento missed your brilliant assist. Since I started learning how to be a python prompt engineer, I wonder if I can get my books by using the browser accessible https://read.amazon.com/kindle-library? What do you think?
