Hey, I'd like to mention Cool Cats, a book of R&R photos and some essays. It goes from the 50s up to the early 80s.
Also, some subculture books: Subculture, the Meaning of Style, by Dick Hebdige
Skinhead, by Nik Knight [this guy does fashion photography now]
Reggae International, by Stephen Davis and Peter Simon
Mods, by Richard Barnes [he also did the who, maximum r&b]
and a fiction book, Absolute Beginners, by colin macinnes [early mod]
