Yeah, old python 2 books might not be worth anything now, but I love ancient tomes about batch files, OS/2, perl, or fortran. Even old linux books can be great

Yeah, old python 2 books might not be worth anything now, but I love ancient tomes about batch files, OS/2, perl, or fortran. Even old linux books can be great to flip through. Anything with early web stuff is also really interesting. The ones with long lists of URLs in the back (even with them being mostly long dead), chapters on archie or gopher/veronica... it's very cool history. Books from the early days of the internet when it was all potential and exploration, before greed and surveillance capitalism set in, are both nostalgic and inspiring.
