I live in a small town and the only library we have is school one. Sometimes I visit bigger town but I have not used it even once, most the books I have read is pdf, some of that was bought and some was not. I will try library way next time I have time.
If talking about sending these to me not to library, I do not want anybody to pay for that, also I can pay in crypto or card for some specific books I appreciate and for post inside US. My preferred fields are cryptography, probability theory / statistics, game theory, and anything about old / obsoleted programming langs: Cobol, Fortran, Perl, also compiler design. Moderately desired is anything about electronic design and signal processing. Absolutely super desired is Turing Omnibus, GEB, TAPL and anything about Lisp.
