to our own. Accordingly, the bibliography was expanded to include 

 material published anywhere in North America and including the 

 West Indies and the Hawaiian Islands. 



The International Union recommended that the national bibliog- 

 raphies be arranged according to a uniform classification and format. 

 The material listed in the present bibliography is not so arranged, 

 however ; first, because agreement on the classification was not reached 

 until after the bibliography was well under way, and second, because 

 the classification applied inadequately to American forestry. Instead. 

 a classification was adopted that follows in many details the one used 

 by the Forest Service, which in turn follows in part the classification 

 suggested by a Committee of the Society of American Foresters. 3 



The format does not follow that recommended by the International 

 Union, but instead follows the one used in other bibliographies pub- 

 lished by the Department of Agriculture. 



The bibliography contains the titles of only the more permanent 

 literature on forestry, using the term in a broad sense. It includes 

 a wide variety of subjects having to do with the forest and its prod- 

 ucts, stress being laid especially on the more technical phases of for- 

 estry practices as such. On the other hand, many topics pertaining 

 to botany, soils, geography, and similar fields, which, though im- 

 portant or directly related to forestry, are not essential to it, are 

 given only passing attention or omitted entirely, since the inclusion 

 of titles in these related subjects would have made the compilation 

 task altogether too great. Range management, highly important in 

 the management of the western forests of America, is omitted because 

 a bibliography on this subject has been published separately. 4 



Because it would obviously be impossible for any one individual to 

 pass upon the lasting value of all publications in such a wide field 

 of science as is embraced in forestry, each section was reviewed by 

 one or more foresters having special acquaintance with and knowl- 

 edge of that particular field, and titles were included or eliminated 

 upon their recommendations. In many doubtful cases the original 

 articles were consulted before a decision was reached. In case of real 

 doubt as to the merits of an article, the title was included. Many 

 foresters throughout the United States in Federal, State, and private 

 activities and engaged in research, teaching, and administration thus 

 have contributed heavily to this bibliography. Although this proce- 

 dure has not entirely eliminated all error, it has done much toward 

 retaining worth-while material. 



In addition to the library of the Forest Service in Washington, 

 D. C, the catalog of which probably contains more articles on for- 

 estry than that of any other library in America, the Library of 

 Congress in Washington, D. C, and the British Columbia Library 

 at Victoria, B. C. Canada, were referred to freely. Libraries at 

 schools of forestry, particularly those at Yale and Cornell Universi- 

 ties and the Universities of Toronto, Michigan, Minnesota, and Cali- 

 fornia provided additional titles ; libraries of other institutions where 

 forestry material might be found, such as the University of Chicago,
