textbooks

[Topspin715]

I am curious to learn the basics of a lot of general subjects for practical purposes.  I can be a nerd and sometimes like reading textbooks to get up to speed really quickly on a subject.  Does anybody have any recommendations on how to pick the best one or two textbooks for a subject in a field where there are many?  Also, where is the best way to get them?  Online used website or maybe certain libraries or online repositories?
