Rory Reynoldson has recently published a small Pocket Reference for the Savage 99 lever-action rifles. This is a collector's resource that includes the particularly important tabular sort of data for keeping on hand at gun shows and the like - serial number ranges, model designations, calibers, barrel length option, engraving patterns, and so on. While not an ideal general reference for the Savage 99 (for that, I suggest David Royal's book), it is a helpful tool for serious collectors of the 99.
