Williams, Gary. Air Racing Results Vol I (1909-1918), Vol II (1919-1927) and Vol III (1928-1930). Phoenix, Arizona, C&G Publications, July 6, 2006 Edition. Privately printed on 8.5x11", both sides, each volume about 200 pages (unpaginated), clear mylar cover, plastic comb bound. Race results (both closed course and cross-country) are listed and, when available, a color picture of the race program cover is shown. I believe there are actually 6 volumes in a complete set and this is an earlier edition. This is the definitive reference on air races and is no often offered for sale. A must for the avid air race collector.
