I'm pretty handy at sourcing ebooks that aren't listed on LibGen/Zlib.
Theory and history books will be given preference if I get inundated with requests but I'll try to find whatever you're looking for.
Comment with the full title and author of each book, each on a separate line.
Please don't request "everything from x author" or "the books in the x series" because then I have to guess as to which books are in that series or I have to look up every book myself, which adds a lot of unnecessary work for me.
