The Las Vegas Ambassadors Collection (1968-1985) primarily consists of a scrapbook, newspaper articles, and photographs documenting the activities of the Las Vegas Ambassadors youth singing group. The materials were compiled by Harry LaFavor, the Ambassadors' business manager, who co-founded the group with Norman Kaye and Richie Astone to promote a positive image of Las Vegas. The collection also includes a songbook, vinyl record and ¼” tape recording, and promotional materials.

The William Flangas Srapbooks document his anti-smoking efforts in Nevada from 1974 to 2014. These materials include correspondence, articles, copies of assembly bills, newsletters related to smoking and health, and newsletters related to non-smokers.

The Clyde F. Merrick Photographic Slides (approximately 1971-1979) contain color photographic slides taken by Clyde F. Merrick, longtime resident of Las Vegas, Nevada. The majority of slides in this collection depict signs for different businesses around Las Vegas including the Las Vegas Strip and the Westside. Some of the businesses documented in this collection includes Fong's Garden, Leon's Shear Magic Beauty Salon, Lucas and Son's Antiques, Dick's Tricky Trikes, Mohan's Custom Tailors, the Twenty Grand Club, Owens TV Repair, and Caesars Palace. The collection also documents a variety of different types of businesses around Las Vegas including bars and nightclubs, beauty salons, car washes, gas stations, and restaurants. Merrick was also a car racing hobbyist and a number of slides in this collection depict what is presumed to be the Las Vegas Speedrome racetrack (later known the Las Vegas Motor Speedway). This collection also includes photographs of locations outside of Las Vegas and Southern Nevada.
