    Abstract
    An investigation of tools, techniques, and methods for the evaluation of interactive library catalogues is described, with emphasis on diagnostic methods and on use of the catalogue in a wider context of user information seeking behaviour. A front-end system (Olive) was developed to test verious enhancements of traditional transaction logging as a data-gathering technique for evaluation purposes. These include full-screen logging, pre- and post-search, online/offline, and in-search interactive questionnaires, search replys as well as talk-aloud. The extent of subject or hybrid searching activity as opposed to specific item searching is also highlighted
