Recent work in the modern history of sexuality, now an established field of inquiry, is characterized by particular approaches to the interpretation of modernity and selfhood. In general, and in contrast to previous approaches, the books under review treat modernity as a localized process with specific effects. Sexual identity is understood in a similar way, as a phenomenon bounded by locality, class, age, nationality, gender, patterns of sociability, and other contextual factors. As such, speaking of sexual identity as a unitary entity, or as something that has historically been structured by an opposition of homosexual/heterosexual, no longer makes sense. In fact, the homo/hetero binary is of much more recent vintage than has been hitherto thought. These histories of sexuality challenge historians of all kinds to rethink the nature of categories like selfhood, identity, and modernity.
