The Gerald Martin Best Collection was donated to the Museum Library in 1986. Mr. Best (1895-1985) was a railroad photographer, modeler, and the author of numerous histories such as Iron Horses to Promontory and Nevada County Narrow Gauge. The photograph collection includes over 70,000 prints and 55,000 negatives, documenting more than 2,500 North American railroads. Prints are arranged by corporate name. Nearly all of the images are roster shots of steam locomotives. These have been further arranged in road number order. There are also train shots, and some coverage of diesel power and rolling stock. Not all prints have negatives, nor do all negatives have prints. A photocopy of the cards Mr. Best used to record date and location identification is available; however, it is not always possible to precisely link this data with a specific print.
