This page has all the GCP textbooks I can get ahold of. So, if you wanted them for free, here you go!
Note: Due to me not expecting anyone to actually care about this site, literally only two books have the PNG backgrounds so far. But I am working to get this number up
Almost all of these books have been acquired though people who are willing to share their CGP codes, or have sent their book files to me. If you have a book that's not on this list, don't hesitate to get in contact and I'll walk you through how to get the files to me! Opien3459@gmail.com If you have any questions, issues or bugs, also get in contact. If I don't reply within three weeks, shoot me another email, I've probably missed your message.
