Introduction 



This computerized bibliographic analysis closely follows the principles and proce- 

 dures that were developed to produce the initial 1968 volume. In order to make the 

 bibliography virtually self-explanatory, and therefore easier to use, a finding index with 

 detailed cross references has been added, as well as an index of systematic categories 

 and an alphabetical list of serial titles. 



In the preparation of this volume, the following persons and institutions have pro- 

 vided vital assistance and support: Miss Louise Schultz and her associates of the 

 BioSciences Information Service, Dr. Donn E. Rosen, Dr. Gareth J. Nelson, and Mrs. 

 Vivian Joan Oleen of the Department of Ichthyology, The American Museum of Nat- 

 ural History, and the Office of Science Information Service of the National Science 

 Foundation (Grants GN-658.1.2.3.4) . 



During 1972 and 1973, a cooperative arrangement was negotiated between the Dean 

 Bibliography of Fishes and The Zoological Record of The Zoological Society of London 

 that will result in the incorporation of the Bibliography into the Record as Section 15 

 Pisces. The Zoological Society has accepted the Dean Bibliography in its computerized 

 form and is also planning to utilize its system of indexing and computerization in the 

 production of all the sections of the Record. Transitions from one method of publication 

 to another are difficult at best, and the establishment of a joint publication will entail 

 many small but necessary changes in the indexing and presentation of information. The 

 period of transition will occupy the time that had previously been relegated for the 

 preparation of the 1970 edition of the Dean Bibliography. As a consequence, there will 

 be a lapse of one year in the production of the Dean Bibliography of Fishes and the next 

 edition will appear as the 1971 Pisces section. The 1970 edition of The Zoological Record 

 will contain the Pisces section produced by the regular method of that publication.
