State historian Marshall Trimble collects memories from his travels throughout Arizona, in addition to the mementos that line his bookshelves. Trimble’s love for the 48th state emanates from him, and stories of its earliest days – and his personal reminiscences of his Grand Canyon State childhood – bubble out with palpable excitement. “My hobby is Western history in Arizona,” says Trimble, who also lectures on Southwestern history at Scottsdale Community College. “It’s all I do.” His latest book, Arizona Oddities: Land of Anomalies & Tamales (Arcadia Publishing, $23.99), cobbles together uniquely Arizonan historical tales. He let us peruse his personal bookshelf to talk about his favorite reads and objets d’art.
