New York: The Free Press, 1967. Twelfth Printing. Octavo. 22cm. Publisher's charcoal grey cloth, titled in silver gilt to spine. Dustjacket. 198pp. A clean, fresh copy, with the lightest of wear to the cloth, and some light marginal scuffing and rubbing to the dustjacket, with one small triangular chip to the base of the spine panel. A very good, bright copy indeed. Internally clean, fore-edge untrimmed. A serious an significant sociological study into "the widespread crisis of juvenile delinquency" in America in the 1950's. Perhaps not so much a mystery any more, now that we understand that trauma, neglect, social and financial disparity, cultural instability and lack of opportunity cause problems for young people, but for the time, groundbreaking. The spectre of youth unrest was described at the time as an 'epidemic', and spawned a whole genre of fiction, music, aesthetics and academic attempts to understand it. Cohen's book can be numbered up there amongst the studies that had some lasting effect, and his Universal Theory of Delinquency is still discussed today. Although we now instantly understand that members of disenfranchised, marginalised groups will set and pursue their own criteria for success, security and status in opposition of "mainstream" social concepts of the same, we do so partly as a result of researchers like Albert Cohen lighting the fuse.
