This paper reviews 17 years of research in Library and Information Science in Spain. The total production of two major Spanish periodical publications in the field were analyzed from 1977-1994 according to productivity variables and thematic content. The Spanish research output seems to concentrate in the areas of information retrieval, description of services, and studies of scientific communication. However, there are differences in the concentration of topics per journal studied. 681-697 Abstract Words are problematic for describing images, but they are a convenient and traditional way of describing requests.
Users can given voice to their reactions to images-how well they suit needs.
Shifting focus from description of documents to description of reactions is accomplished by gathering verbal captions and responses to images. User generation of captions and verbal responses within a collection of 300 diverse images is demonstrated and analyzed. Issues of larger scale analysis, implementation, and possible shifts in understanding of representation for retrieval are discussed. In order to determine whether medical students can recognize when an information need has been fulfilled and when it has not, this study examined the quality of medical students' confidence estimates in answering short-answer questions dealing with bacteriology, based upon their personal knowledge alone and what they were able to retrieve from a factual database in microbiology. Twelve students, assessed over three occasions, remained in the final sample.
