4 MISC. PUBLICATION 4 01, TJ. S. DEPT. OF AGRICULTURE 



floras of the world, and similar but briefer lists have appeared in 

 various textbooks on systematic or other phases of botany, but none 

 of these represented any real search of the voluminous available 

 literature. 



The part of this list now published, covering all the world except 

 Europe and Asia and the islands closely associated with them 

 (namely, those north of 40° north latitude in the Atlantic Ocean 

 and north of 30° north latitude in the Pacific), includes about 2,597 

 primary titles and 428 subsidiary titles (supplements, reviews, etc., 

 as well as the few works listed as not available for examination). 

 At least as many more papers have been examined and rejected 

 as not fulfilling the promise of their titles. 



The list is based in the first instance on the classified subject 

 catalog of botany in the library of the United States Department 

 of Agriculture, begun in 1906 under the direction of the late Dr. 

 Frederick V. Coville by Marjorie F. Warner and Alice C. Atwoocl, 

 and continued by them and their assistants. This catalog provides 

 a fairly complete index to the systematic and economic publications 

 of the world for the last third of a century, as well as to much of the 

 earlier literature. Practically all the pertinent works on the shelves 

 of the libraries of the Gray Herbarium, the Arnold Arboretum, and 

 the New York Botanical Garden have been examined independently 

 by one of the authors, and the titles given in the bibliographies of the 

 papers cited in the present list have been checked. The geographically 

 arranged lists in the Bradley Bibliography, 4 the Catalogue of the Li- 

 brary of the Arnold Arboretum (vol. 2), and the publications of the 

 Lloyd Library 5 have also been utilized, as well as Bay's Bibliographies 

 of Botany. 6 Certain series of periodicals have been gone through, but 

 no complete examination of the botanical periodicals of the world has 

 been attempted, nor have the unclassified catalogs of the libraries 

 of the Kew Herbarium and the British Museum been searched, al- 

 though they would, no doubt, provide some additional items. 



After the bulk of the list was essentially completed, a search 

 through the principal periodical bibliographical publications added 

 a considerable number of mostly minor titles, which previously had 

 been overlooked or rejected. The publications examined for this 

 purpose include: Biological Abstracts (vol. 1-13, pt. 8), Botanical 

 Abstracts (vol. 1-15), Bohnensieg's Kepertorium annuum literaturae 

 botanicae perioclicae (vol. 1-8), Botanisches Centralblatt (vol. 1-175. 

 heft 6) and its Beihefte (vol. 1-9), Bulletin de la Societe Botanique de 

 France (vol. 1-86, pt. 2), Engler's Botanische Jahrbucher (vol. 1-70. 

 pt. 3), Fortschritte der Botanik (vol. 1-8), International Catalogue of 

 Scientific Literature (vol. 1-14), and Just's Botanischer Jahresbericht 

 (vol. 1-57, heft 1).
