contents	A Zipfian Model of an Automatic Bibliographic System: An Application to MEDLINE. Fedorowicz, Jane Citations (References) Databases Information Retrieval Mathematical Models Online Systems Spelling Statistical Analysis Statistical Distributions Subject Index Terms Word Frequency Derives the underlying structure of the Zipf distribution, with emphasis on its application to word frequencies in the inverted files of automatic bibliographic systems, and applies the Zipfian model to the National Library of Medicine's MEDLINE database. An appendix on the Zipfian mean and 12 references are included. (Author/JL)
