Also listed as Manuscript Codex 1028, this collection is comprised of 26 volumes of material containing research data from the Committee, and an additional box of sources. Volumes 1-24 consist of the hand-written records of the researchers' observations at particular sites and venues of supposed criminal activity. Volumes 25-26 are the records of court cases that resulted from these research endeavors and primarily address pandering allegation. The additional box contains a collection of ledgers that holds lists of addresses, the purpose of which is unclear. It is possible that these ledgers were taken out by investigators to keep track of addresses that they visited in any given evening, though there are no dates recorded to clarify. Many of them are empty or very nearly empty.View Online Collection and Finding Aid
