It’s all there in the 1992 study, recently made available on the web:
A 1992 survey of 5,000 U.S. librarians, long withheld by a professional journal, found one in five respondents had engaged in sexual trysts among the stacks.
Will Manly, who said the New York-based Wilson Library Bulletin withheld the results of his survey in 1992, published results recently on his Web site indicating 51 percent of librarians in the early 90s were willing to pose nude for money and 61 percent of respondents admitting to renting an X-rated film, the New York Daily News reported Monday.
