AB This study presents author cocitation analysis from the
   information retrieval research field from 1987 to 1997. The
   data were retrieved from Social Scisearch via Dialog. The top
   40 authors were submitted to author cocitation analysis to
   yield the intellectual structure of information retrieval. The
   resulting multidimensional scaling map shows 1. identifiable
   author groups of information retrieval, 2. locations of these
   groups with respect to each other, 3. the extent of centrality
   and peripherality of authors within groups, 4. proximities of
   authors within group and across group boundaries; and 5. the
   meaning of the axes of the map, which adds interpretation.
   Factor analysis was used to reveal the extent of the author's
   research areas. Statistical routines included ALSCAL,
   clustering analysis and factor analysis. Cocitation analysis of
   authors offers a good technique that contributes to the
   understanding of intellectual structures in the sciences and
   possibly in other areas to the extent that those areas rely on
   formal scholarly communication (serial publications).
