He wrote two books, How to Protect Your Child from the Sex Criminal, and Sex, Science and Sin, and was instrumental in reforming Oregon's sex crimes laws in the 1950s. The collection contains correspondence, including one folder devoted to letters from Alfred C. Kinsey; notes on sex crimes cases investigated by Biggs; and copies of his two books.
