UFO Researcher David Marler delivered this year's spring Willard lecture, "UFOs at UNM: A Skeptical Believer Presents His Research," at the UNM University Libraries, May 31, 2017. Marler spoke about how he uses UNM’s collections and other resources to research UFO phenomena, including the mass sighting in Farmington, NM, in March 1950 and the “Battle of Los Angeles” in 1942. Marler has one of the largest personal collections of UFO books, journals, magazines, newspapers, and case files from around the world that covers the last 65 years. Based on this research, he published the book, Triangular UFOs: An Estimate of the Situation in 2013. He has donated his extensive collection to UNM Libraries as an estate gift.
