eh. For who want's to get deeper/broader view, there's a "bible" on UX.. called "Usability engineering" by Jakob Nielsen ~1993 [0].

IMO The first 2 (two) chapters are, like, mandatory - the what and the why. The rest, is mostly details - how. (but it has even how to organise random-street-user-tests and what to look for in those, etc)

Although, looking at recent 10 years of (software-or-car) UXs, i feel noone reads these anymore :/ Sadly.
