Traveller is a series of related science fiction role-playing games, the first published in 1977 by GDW. Marc Miller designed Traveller with help from Frank Chadwick, John Harshman, and Loren Wiseman. The original Traveller gamebooks were distinctive half-size black pamphlets (the so-called "Little Black Books" or "LBBs") produced by GDW. The main rules were detailed in three such booklets, sold as a boxed set, while the same format was used for early support material, such as the Adventures, Supplements and further Books. Later supplements and updated versions of the main game system introduced full-sized booklets, complete re-writes of the game system, and significant changes to the Third Imperium. The original version was designed and published by GDW in 1977, sometimes called "Classic" Traveller. The core rules originally came as three distinctive "Little Black Books," in a boxed set. Supplemental booklets included "advanced" character generation, capital ship design, robots, and more.
