Bibliographic coupling between scientific papers Abstract This report describes the results of automatic processing of a large number of scientific papers according to a rigorously defined criterion of coupling. The population of papers under study was ordered into groups that satisfy the stated criterion of interrelation. An examination of the papers that constitute the groups shows a high degree of logical correlation.

A proposed structure for displayed information to minimize search time through a data base Abstract Minimum user search time is selected as a relative measure of efficiency for evaluation of data base classification structures. For two common structures with similar characteristics, a “table of contents” format and a “decision tree” format, a visual search time formula is derived. The optimal shape for a data base classification structure is shown to be narrow: three to five information items to be selected at each successive level of the structure, with as many levels as necessary for the data base size. This shape is compared with those of classification structures commonly in use and, based on search time parameters developed, recommendations for librarians and other information classifiers are made.
