This is an essential book for historians of sexuality (and gender). These articles present balanced, stimulating accounts of various key themes, such as cities, marriage, childhood, etc. While most simply do their job, some are absolutely pivotal. Chris Waters’ article on sexology made me realise, for the first time, how deeply intermingled the origins of the historiography of sexuality are with sexology — and especially with the reformist strain of early sexology. In which ever ways we might protest, the history of sexuality is always perceived to have some say in contemporary arguments about the legitimacy of particular identities and practices. This leads to Alison Oram’s article on cross-dressing in history. Her careful summary of discussions about lesbianism and sexual inversion at the turn of the twentieth century display all the complexities of gender’s relationship to sexuality; her careful interweaving of transgender perspectives suggests the nascent and blooming areas of research which are now coming to prominence.
