CLASSIFIED INDEX TO TITLES 



Prepared by Gladys O. Visel 



The index that follows is intended as a finding-index to the titles and 

 authors of the publicatons listed in the foregoing pages. It does not attempt 

 to go beyond the titles to index the detailed contents of the papers, as this 

 would require a work of many times this size.* For example, under the 

 locality California a user of the index would not be referred to every Museum 

 publication that might include California in its scope. Localities are included 

 only when they appear in the titles. The large categories America and North 

 America have usually not been indexed even when they appear in the titles, 

 as they are too numerous and general to make their indexing of any value. 

 Countries of South America, Africa, Asia, Australia, etc., generally have 

 not been included under the continent except where the latter appears in 

 the title; these countries appear in their alphabetical place in the Index. In 

 general, subjects are broken down into the main divisions of curatorial and 

 research work with which the National Museum is concerned and which is 

 reflected in its publications. Here again the user should not expect to find 

 under any one subject a complete catalog of information. A general paper 

 on insects, for example, might contain information on many families and 

 groups, but since the names of these would not appear in the title of the 

 paper as listed they would not appear in the index (except perhaps in other 

 connections). A paper entitled "The Birds of Ecuador" would be indexed 

 under Birds and under Ecuador, but not under Warblers although this group 

 might occupy a large portion of the paper; whereas a paper on "The Warblers 

 of Ecuador" would be indexed under Birds, Warblers, under Warblers 

 {see Birds) y and under Ecuador, Warblers, but not under Ecuador, Birds. 

 In other words, although this is a classified Index, the user must remember 

 that in the natural-history sections entries have not been reassembled under 

 the geographic groups for the sake of systematic completeness; he will find, 

 for example, under South America, entries under Hymenoptera, Diptera, 

 moths, etc., but these have not been assembled under Insects. The reader 

 will find also that absolute uniformity of treatment has occasionally been 

 sacrificed for the sake of brevity and expediency. An instance of this will 

 be found in the class Insecta, which because of its size has been subdivided 

 into its various orders; in other classes of animals this has not been done. 

 Cross-references have been freely used to avoid duplication and to reduce the 

 size of the index. 



* A comprehensive, detailed index of National Museum publications has been in preparation in 

 the Editorial Office of the Museum for several years and is completed to the year 1900. It is in the 

 form of a 3-by-5 card file and comprises to date about 235,000 cards. It may be consuUed in the 

 Editor's Office, Smithsonian Building, by anyone interested.
