The free web textbook list

The following is a collection of free ***legal*** html/web-based textbooks on various subjects that i've encountered on the internet. Free web based textbooks are really cool, and i think there really should be more of them on the internet. In the meantime though, im going to greedily store links to every single one i come across right on this page here >:D FYI though, I have not read through most of these, this list is mainly just me exersizing my data-hoarder tendencies over any sort of curated recommendations list.
