This evaluation was similar to the first in that participants used the ENQUIRE system for periods which allowed them to complete a single search with a query of their own. After searching, they were given a structured interview and their responses recorded on a questionnaire form.
Participants were again gathered from LBS library and recruited as they approached the catalogue terminals. Nineteen users participated. Data, software and equipment resources were the same as those used in the first test. The new material was a pre-test questionnaire (Appendix H) and a post-test questionnaire (Appendix I).
