Under Paul Gebhard's leadership, the interview based research project continued, resulting in the publication of Pregnancy, Birth and Abortion[11] and Sex Offenders: An Analysis of Types.[12] Other significant publications included JoAnn Brook’s Sexual Nomenclature: A Thesaurus[13] and Alan Bell and Martin Weinberg’s Homosexualities: A Study of Diversity Among Men and Women.[14] Additionally, in response to criticism that Kinsey’s original data was biased and not well defined, Gebhard and Johnson wrote The Kinsey Data: Marginal Tabulations of the 1938-1963 Interviews.[15] To honor its founder, the Institute for Sex Research was renamed The Kinsey Institute for Sex Research in 1981.[16]
