From an Overview of Traveller Material appendix in Book 0: An Introduction to Traveller:
Playing Traveller situations is a primary focus for Traveller players, and adventures are intended to allow players to begin immediately. Each includes a brief introduction, a cohesive central theme, and a wide variety of materials intended to direct the players and the referee through one or more Traveller situations. Adventures are 48 page (or longer) booklets, with plans and drawings, background data, and other important information.
