In order to evaluate its library instruction program, a postal survey was conducted of students who participated in library orientation courses at the Technische Universitaet Wien (Technical University of Vienna) in Austria during the winter term of 1982/83. The orientation courses consisted of a 1-hour lecture on use of the library and a library tour. A total of 93 responses to the survey were received. Most students indicated that the information offered in the orientation courses was sufficient for their needs (90 of the 93 respondents) and that use of the library would help them complete their academic coursework (88 respondents). However, only a few students indicated an interest in further subject-oriented library instruction (9) or a willingness to participate in further discussion of the introductory library instruction (5). A sample questionnaire is included in this paper, which describes the library orientation courses and the methodology and results of the evaluation survey. (Author/ESR)
