The Story
The second edition was published in two folio-sized volumes, one targeted at Players (184 pages, Basic Edition and 400 pages, Master Edition) and the other at Game Masters (180 pages, Basic Edition and 462 pages, Master Edition), both in soft cover.
  In each case, the Basic Edition was a subset of the Master's Edition (and the DPI catalog listed the additional Master's material as an Expansion volume).
