Relative cost and effectiveness of techniques for preparing a computer compatible data base consisting of approximately one million words of natural language are outlined. Considered are dollar cost, ease of editing, and time consumption. Facility for insertion of identifying information within the text, and updating of a text by merging with another text are given special attention. It is concluded that Magnetic Tape Selectric Typewriter (MTST) and Telterm2 (a cathode ray rube terminal) are two highly effective methods of text preparation. The decision of which to use on a particular project would depend on available funds and possible peripheral uses for the equipment. Criteria for making such a decision are discussed. (Author)
