>>612826because i think this is a really good topic (i made a thread like this about a month ago) and because i feel particularly nice, i'll zip and upload my personal /out/ pdf folder.
i have crappy up speed, so it'll take ~40min for the 220MB zip, here's a list of content to hold you over.
will keep lurking, always open for good recommendations. and please people, if you recommend, tell us why this particular book is good, and in case you post a link, please make sure it's a decent version of the pdf - as i have with mine. for most books, there are many scans of varying quality out there!
