The collection holds over 10,000 titles to include 7,750 electronic documents, 1,080 archived periodicals, 80 journal titles, 300 audio visual materials and access to 80 commercial databases. The library serves as a repository for polygraph archives and holds the largest collection of polygraph history in the United States. The Special Collection includes Leonarde Keeler’s collection of books and personal effects, donated by the Keeler Polygraph Institute, Chicago, Illinois.
