From the introduction:
While assisting in the collection of problems with the initial FFE release of the Classic Traveller CD-ROM, there were issues that came up with the rules, and questions that people asked me for answers from Marc Miller. As Marc began preparations for a revision of the FFE Classic Traveller CD-ROM, it became obvious that there was a need for collecting the errata from the earliest edition of Traveller. This document not only represents hours of personal research, but great amounts of contributions and suggestions by Classic Traveller fans on the Internet, particularly users on the Citizens of the Imperium forums.

This document is intended as a LIVING document—the intention is to allow the Traveller community to continue to add to it, making it available for future Classic Traveller players and referees.
