Existing literature in the technical publications field indicates large deficiencies in many areas. Technical writing, per se, is only a small portion of the technical publications field. This chapter, Research and Liaison Activities for Technical Publications, is an attempt to fill part of that gap. Research for raw source data inputs for the preparation of a technical manual involves special knowledge and techniques in dealing with other groups and departments. Since technical writing also requires support services such as art, editing, typing, proofreading, and production, liaison activities with such groups require knowledge of their special needs.
