The Texas Information Exchange (TIE) is a state-wide library network organized in 1967 for the purpose of sharing resources among Texas libraries. Its membership includes 37 college and university libraries, the Texas State Library, and ten public libraries that serve as Major Resource Centers in the Texas State Library Communications Network. In April 1978, the members of TIE were surveyed on their use of computer-based reference services; this report provides a summary of their questionnaire responses concerning 15 different topics, numbered to correspond to the questions on the survey form: libraries providing computer-based reference services, vendors and numbers of searches, data bases searched most frequently, average search time, organization, equipment, marketing, users, financing, evaluation, impact, SDI or current awareness services, batch searching, numeric or statistical data, and future plans. The survey form is included. (Author/JD)
