LIBRARY. 437 



In tlio Bureau of Plant Industry bibliograjihios in 128 manuscripts, 

 ■comprising 2,125 references, were verified and edited. A cheek list 

 of the State experiment station publications on plant pathology, 

 Avhich is to l)e issued in mimeographed form as a number of the 

 "Bibliographical Contri])utions " of the library of the Department 

 of Agi-iculture, is in process of preparation, as is also a check list of 

 the publications of the Bureau of Plant Industry, and all offices 

 and divisions which were combined to form the Bureau in 1901. 

 The absence of the librarian for the larger part of the year delayed 

 the comj^letion of these two lists, but it is hoped that they will both 

 be completed and be ready for mimeographing in the near future. 



The Library of the Bureau of Plant Industry, in cooperation with 

 Miss A. C. Atwood, has continued to prepare the index to the "Lit- 

 erature of plant diseases'' which is published montldy in ''Phyto- 

 pathology" and has also continued the preparation of the mimeo- 

 graphed list of "CmTcnt author entries" for articles in current period- 

 icals of interest to the Bureau. 



It seems fitting to mention here the important ])ibliographical 

 projects carried on by Miss Marjorie F. Warner and Miss Alice C. 

 Atwood, bibliograpljcal assistants of the Office of Economic and 

 Systematic Botany of the Bureau of Plant Industry, as theh- work 

 is closely allied with tiie Bureau library. Tiieir ^^•ork on the index 

 of botanical illustrations, the bibliograph-V of horticulture, and the 

 union catalogue of botanical literature, which have been described 

 in previous reports, was continued during the year. The last of 

 March a list of abbreviations of works to be included in the new 

 edition of Pritzel's Iconcs was received from Dr. Otto Stapf, of Kew, 

 editor for the Royal Horticultural Society, and a large amount of 

 time was spent in going over the list with reference to possible omis- 

 sions and desirable additions. The results of this cooperative work 

 are still in tl e making. 



.VnothfT piece of verification work requiring much time was the 

 correction of the errors in the "Bibliograpln- of take-all" by F. L. 

 Stevens in the Illinois Laboratory of Xatural lOstory (Bulletin vol. 

 13, Ai-t. IX, Oct.,_ 1 919). These corrections have not Ijeen published, 

 but arc available in typewritten form to libraries or scientific workers 

 that may wish. them. An article by Miss iVtwood on the ''Errors 

 in Linthau's Thesaurus and Saccardo's Syllogc" was published in " My- 

 cologia" vol. 12, p. 169-i 71, May, 1920. Miss Warner's paper on the 

 •• Bibliogja])hical opportunities in liortioulture, " wliicli was read be- 

 fore the Agricultural Libraries se('tion of the American Library Asso- 

 ciation in June, 1919, was published in tlie Proceedings of tlie Asso- 

 ciation foi- 1!)19, p. 178-184, and also in tlie Librarv Journal, under 

 the title, "The literature of horticulture," vol. 44, p. 766-776, 

 JVcember, 191'). 



The bibliographical work of the vState Kelations Service hbrary 

 described in previous rep(»rts was <-<)ntinued along the same lines 

 (hiring the year. 



In tlie spring of 1920 tlie library was offered the use of a 

 page in each numl)er of tlie "Agricultural Ind<>x" to be called 

 ■• Afjjricultural Librarv Notes." These notes will be principally 

 bibliogiaphical in cliaracter. Tlie first number, for which contribu- 

 tions were made by the main librarv and the bureau libraries.
