I want to give to my pet books to read but I want to know what books are missing, someone know a guide for know the comparation of missing books?

Make an account at Subetalodge, you can add your pets' names and add their already-read books to their checklist. Books read you can do by putting in the URL of the page and then changing the page number at the end (but you have to do every page separately), some other lists you would need to add with the source code.

thanks a lot, I will try :D

Let me know if you need more specific help, I kind of tried to keep it simple but I'm afraid I might not have been detailed enough xD

that was easy tanks!

Ah, I'm glad you figured it out :D There are instructions on the mass add page too for that, but it's pretty straightforward since you can just use the URL for that (and then move to page 2, paste that URL and then just change the number at the end until you run out of pages).

thanks! I spent 700k in books already my pet has 328 books xD

Unlocked Book Worm! Have a pet who has read # different books.
