Adding Sexuality / Sexology

As one might expect in a bibliography that originated in 1912, there was little or nothing about sexuality or sexology in the bibliography, even in the 5th edition of 1991. There were only a very few works: Freud (1905) Havelock Ellis (1900-1928),  Kraft-Ebing (1886), Forel (1905). These were included under Psychology. If you count prostitution under sexology there were also Parent-Duchâtelet (1836) and Henriques (1961-68) and the 20th century English translation, rather than the original French edition, of Lacroix (1851-53). These were indexed under Public Health. Sex appeared in the subject index chiefly with respect to genetics and the science of reproduction.

As of today there are 13 entries under the main subject and 6 under "History of".
