- Thrapp, Encyclopedia of Frontier Biography, p. 905: "McGinty took part in one cattle drive in 1889, from the south Plains to Montana, but most of his career was spent breaking horses, sometime more than 400 a season."
- Shirley, West of Hell's Frings, pp. 142-143: " 'I [McGinty] got a glimpse of Daugherty's guest later, at a distance, and recognized Bill Doolin. I had worked with him on the Bar X Bar in the Triangle country. I didn't know about his trouble then, so said nothing'."
- Walker, Rough Rider, pp. 137-189: "A favorite among the cowboys was 'Little Billy' McGinty, a wiry Oklahoma wrangler and bronc buster. Among the many stories that circulated about McGinty, a favorite concerned his absolute and unwavering inability to stay in step on the parade ground. After repeated chewings-out, the hangdog Little Billy finally implored, 'Let me git my pony. I'm purty sure I kin keep in step on horseback!' "
- Roosevelt, The Rough Riders, pp. 162-163: "Little McGinty, the bronco buster, volunteered to make the attempt, and I gave him permission. He simply took a case of hardtack in his arms and darted toward the trenches. The distance was but short, and though there was a outburst of fire, he was actually missed. One bullet, however, passed through the case of hardtack just before he disappeared with it into the trench."
- Russell, The Lives and Legends of Buffalo Bill, p. 419: "In 1899 the Rough Riders of the World included sixteen of Roosevelt's Rough Riders, among them Tom Isbell and William McGinty."
- Stewart, "McGinty Boosted for Cowboy Hall": "You could say too that Billy did the first bronco busting shown on a movie film, with a special act arranged for the 1890 Paris world's exposition. In addition to winning a challenge 'world's championship' a bronc busting at Southampton, N.Y.; in a match with Bert Bryan of Arizona."
- McRill, "Music in Oklahoma by the Billy McGinty Cowboy Band", pp. 66-67: "Youngblood was a town-promoter of no mean ability and talked with the group and came up with the idea of calling the band 'The Billy McGinty Cowboy Band.' This was a very natural conclusion since Billy McGinty was known nationwide as one of the very early cowboy of Oklahoma, Texas and Arizona."
