Using PsychInfo review of rape and sexual assault publications, the period of greatest fertility coincided with the establishment (1975) and demise (1987) of the National Center for the Prevention and Control of Rape. To document what has been learned and when, the era in which new rape concepts entered the literature is summarized and important developments highlighted. Then, new investigations that are urgently needed are elaborated. The author expresses concern that current federal investment is insufficient to sustain and expand a science workforce adequate to the tasks ahead. Since 1995, more than $1 billion have been awarded to prosecutors, law enforcement, and community agencies to assist victims of violence. In contrast, between 1996 and 2003, only 14 of 178 (7%) of investigator-initiated grants funded by the Department of Justice and the Centers for Disease Control and Prevention for violence against women had titles pairing the word sexual with assault, violence, abuse, or rape.
