High Guard (Second Edition) (1980)

From Supplement 05: Lightning Class Cruisers, page 12:

Editions of High Guard: There are two versions of High Guard.

The first edition is identifiable by a copyright date of 1979 on the publication data page.

The second edition carries a 1980 copyright date on the publication date page and is a revised, improved, and expanded version incorporating a variety of changes to the first edition. This second edition is an attempt to improve Traveller materials as the opportunity arises. The substance of the new material is also contained in a three-part article contained in the Journal of the Travellers' Aid Society (Issues 6, 7, and 8), under the assumption that the Journal is the best method of dissemination of such material to those players and referees who already have the first edition of High Guard.

From the title page of the introduction to the second edition of this book:

This book is a substantially improved and re-typeset edition of High Guard, Traveller Book 5, which originally appeared in 1979. It contains additions, corrections, and changes to the starship design and combat rules (pages 17 to 52). The introduction and character generation system (pages 1 to 16) remains unchanged from the first edition.
