BIBLIOGRAPHY 



This bibliography contains practically all of the works to 

 which reference has been made in this volume. In addition 

 it contains many other works that have been found of value. 

 While it is not put forth as a complete list of all publications on 

 wheat, it should, nevertheless, serve as a good foundation in 

 all research work on this subject, for it is a fairly exhaustive 

 list of American publications, and also contains many foreign 

 works. An alphabetical list of all authors is first given, in- 

 cluding periodicals containing articles of which the author is 

 not stated, as well as miscellaneous official and unofficial publi- 

 cations. This list gives opportunity for looking up tlie works 

 of any given author. For the purpose of aid in research, cer- 

 tain classifications of works will be found after the alphabetical 

 list. All articles from encyclopedias and dictionaries are 

 grouped together. Under each bureau or division of the United 

 States Department of Agriculture are grouped the publications 

 of that bureau or division. The next three groups are those 

 of the United States census, the Department of Commerce and 

 Labor, and consular reports. Then follows an alphabetical 

 list of the state experiment stations of the United States, with 

 station publications listed chronologically under each state. 

 The publications of the Canadian Department of Agriculture 

 are also grouped together. Finally, there is given a topical in- 

 dex of authors. In general, this index contains only those 

 works which permit of definite classification, and it is arranged 

 on the basis of individual works. Each work is placed under 

 only one topic, the topic which it covers most definitely. The 

 name of an author, however, appears as many times under dif- 

 ferent topics as he has written works on different phases of 

 wheat. This topical index, and, to a certain extent, the classi- 

 fication under the United States Department of Agriculture, 

 will facilitate a topical study of wheat, while the classification 

 of experiment station works will aid in a geographical study. 

 Works of special merit are designated with*. Authors the 

 whole of whose publications are of unusual value are desig- 

 nated witht. There are a few works that are inaccessible to the
