The Peter Collins Papers on International Gaming (1974-2010) consist of materials collected or written by Professor Peter Collins on legalized gambling. The collection includes research papers, industry and government reports, and media reports on the development, legality, economics, and ethics of legalized gambling. Most of the materials focus on gambling in the United Kingdom; the balance of the material covers South Africa, Canada, the United States, the European Union, Australia, some Asian-Pacific nations, and materials not specific to location.

The Stephen Powell Bibliography of Gaming Books Held by UNLV, 1972 consists of Powell's manuscript cataloging the gambling related books of the University of Nevada, Las Vegas library system at that time. The manuscript accounts for all the gambling books held by UNLV and categorizes each under its corresponding type of gambling. A bound published version of his book can be found in UNLV Special Collections.
