As far as I know, all books in the library are out of copyright. If I have made a mistake and you are a copyright holder of one of these books, please send me an email and I'll take it down.
Some of these books were easy to find, some were not. Some I had to reassemble from images of individual page images or resurrect defunct websites and recover them page by page. If you like the books and want me to keep putting them together and sharing them, please consider supporting the page on Patreon.
