Abstract

Examines: the conceptual categories or dimensions of the users' reasons for assigning particular ratings on the value of search results, and the relationships between these dimensions of value and the dimensions of success identified in an earlier study. 40 end users with individual information problems from an academic environment were observed, interacting with 6 professional intermediaries searching on their behalf in large operational systems at the users' own costs. A search was conducted for each individual problem in the users' presence and with user participation. Quantitative data consisting of scores for all measures studied and verbal data containing reasons for assigning certain ratings to selected measures were collected. The portion of the verbal data including users' reasons for assigning particular value ratings from the previous study will be trancribed and content analyzed for the current study
