Archive.org Scanned Book Downloader Bookmarklet

A simple "1-click" javascript approach to downloading a scanned book from archive.org to read at your leisure on the device of your choosing w/out having to manually screenshot every pages of the book by hand. In short it's a glorified "Save Image As..." approach but consolidated down to "1 click". BTW there may be a much better option than this out there - I just built this as an autistic project to see if it would work.

Obligatory Legal/Disclaimer:

By using this script you agree to delete all book files/images after your 1 hour or 14 days is up! I don't support using this script for any other use cases. After all, none of us have ever kept a library book past it's return date, right?
