On a completely end user note, we have found our Discovery service for our Library is not well liked by undergraduate students. The results are too large most of the time (10K+) and they (the user) frustrate easily if they have to learn to customize the search.
Our Information Literacy/Bibliographic Instruction Librarians have stopped teaching Discovery Layer Services and the norm. (We us EBSCO Discovery Service which is a Rolls Royce!). The EDS for us not only searches our local loads (local databases, local electronic resources, online catalogs, DSPACE server) but also all of OhioLINK. It is really overwhelming for them. We still teach traditional Keyword Boolean as the starting point and move to the browse queries and then to the ³pre coordinated searches² such as Library of Congress Subject Headings. Pre-Coordinated searches is a fancy name for Controlled Subject Vocabulary. It will be interesting to see how FAST headings will affect searching as OCLC derives them from LCSH and as ILS¹ begin to index them into browse searching and keyword/boolean searching. I think that Discovery Layers are attempting to compete with Google searching. And the rhetorical question or theoretical question is does discovery have Œdeliverables¹ without drilling down into the results to get what you really came for? Professionally and personally, I do use Discovery, but I¹m a trained professional, not a dilettante in the information seeking world. We are in a major paradigm shift that has truly only begun, and it will be another 15 years before the shift sees true results‹some of them will be tied to societal changes.
