This subseries consists of records related to Lyons' book-length publications. It includes Lyons' books on local and natural history in British Columbia, comprised of Milestones on the Mighty Fraser: Travel Guide to the Historic Fraser Canyon Vancouver-Kamloops (J.M. Dent & Sons: 1950, rev. ed. 1956); Milestones in Ogopogo Land: In Which the Many Wonders of the Land of Ogopogo and Sunshine are Revealed (1957) ; Milestones on Vancouver Island: The Story of This "Island to the West", Its Past and Its Present (Evergreen Press: 1958). This subseries also contains Lyons' popular field guides to the plants of British Columbia and Washington state, including Trees, Shrubs and Flowers to Know in British Columbia (J.M. Dent & Sons: 1952, 2nd rev. ed. 1965); Trees, Shrubs and Flowers to Know in British Columbia and Washington (Lone Pine: 1995); and Wildflowers of Washington (Lone Pine: 1997). According to the "About the Author" section in Wildflowers of Washington, "Chess' first book, Trees, Shrubs and Flowers to Know in British Columbia, published in 1954, was the first non-technical field guide in the province. Two years later in 1956, he wrote a similar book for Washington State. They served for many decades, through many reprints and revisions, and were finally combined into one volume in 1995" (192). The 7 monographs in this subseries are mostly labelled "Work Copy" or "Office Copy" indicating that they are early proofs or otherwise being revised, as the handwritten ink comments throughout attest. The records consist of monographs, manuscripts, research and research notes, correspondence, dust jackets, miscellaneous brochures and maps used for research, one notebook, and electronic records on three computer disks. The three computer disks contain electronic version of the revised manuscript for Trees, Shrubs, and Flowers in BC and Washington from 1994.
