The Commander's Edition of Star Fleet Battles was produced as a box set with counters, map, basic Ship System Display (SSD) sheets and a 96 page rulebook. This is the separate "Rulebook Only" version with a blue 3-ring binder, available for previous owners of Star Fleet Battles who had the counters, map and the basic SSD sheets. The rulebook was designed to be disassembled and put in a 3 ring binder. New rules could then be added to the binder and rule updates and expansions replaced existing pages.
