INTRODUCTION 



Since a first monograph in 1875, the United States National Museum has 

 issued its pubhcations in five series: Special Bulletins, Circulars, Annual 

 Reports, Proceedings, and Bulletins . 



The Special Bulletins, begun in 1892, ceased in 1915; the Circulars, issued 

 initially in 1881, in 1929. The Annual Reports, also first published in 1881, 

 were issued through 1964, when the series was discontinued and subsequent 

 reports were incorporated into the larger annual reports of the Smithsonian 

 Institution. The Proceedings, first issued in 1878, were terminated in 1968 in 

 favor of new subject-oriented series at the Smithsonian instead of the old 

 museum-oriented serial publications. For the same reason, the Bulletin series, 

 begun in 1875, is terminated with the present number. Thus, the volume in 

 hand is the final volume of all the pubUcations of the United States National 

 Museum. 



The first complete list of these pubUcafions, covering the years 1875-1900, 

 was issued in 1902 as Bulletin 51. It bore the title A List of the Publications of 

 the United States National Museum (1875-1900) Including the Annual 

 Reports, Proceedings, Bulletins, Special Bulletins, and Circulars, with Index to 

 Titles. A supplement brought the Usting up to date through calendar year 

 1906. 



In 1946, a cumulative volume. Bulletin 193, was issued, comprising the two 

 earlier lists plus all titles published in the intervening forty years. It bore the 

 shorter fitle A List and Index of the Publications of the United States National 

 Museum (1875-1946). A supplement brought the list up to date through June 

 1958. 



The present volume comprehends the supplement and thus is a continuation 

 of Bulletin 193. 



A word of bibliographic explanation: the Bulletin series carries within it what 

 loosely might be termed two "subseries." The Contributions from the United 

 States National Herbarium (first issued in 1890-1895), although considered a 

 part of the Bulletins, is treated separately because of its independent 

 numbering system. Conversely, the other subseries. Contributions from the 

 Museum of History and Technology (first issued in 1959), does not carry 

 seriation independent of the Bulletins and thus is included in the lisfing of that 

 larger series. 



In the index to fitles, all topics (authors, persons' names, taxonomic terms, 

 general subjects, places) are arranged in a straight alphabetical Hsting. There are 

 as many parallel references to a work as are required by the number of topics 

 in the title. Thus, a single bibliographic entry may be approached through a 

 variety of routes.
