iiiiiiihrr of rut rics wliicli will he iiiV()l\(Hl. Fur the set of Annalesi de 

 hi Science A(/r(»ioiii!tjn(., from 1884 to ll>0;->, the author set will incliido 

 328 cards, costing $3,28, and the coini)Iete set (with author set) will 

 include 844 cards, costing $5,92. The 31 \olunies of LandwirUchaft- 

 J'lche Jahrhi'iclwr^ covering the i)eriod from 18T2 to 1!>03, will recjuire 

 838 cards for the author set, costing- $8,38, and 2,500 cards for the 

 complete set, costing $17. Similarly, for Die Idndivirtschaftlichen 

 Yersuchs-Stationen from 1859 to 1903, 1,378 cards will be required 

 for the author set, costing $13.78, and 4,100 cards for the complete 

 set, costing $27, 



The form adopted for the printed card leaves the classification to 

 the individual, so that the scheme is very elastic both in the matter of 

 classification and of purchasing the cards. The card for a particular 

 article will contain the name of the author, the exact title of the 

 article in the original language, the reference to the page and number 

 of the journal, and in small tj^pe at the bottom, the principal subject 

 or subjects covered b}^ the article. The latter is merely suggestive 

 and is intended as an additional guide to the contents of the article, as 

 the title is freciuently not sufficiently definite. 



No free sets will be distributed either to libraries or individuals. 

 The price charged is barel}" sufficient to cover the cost of printing and 

 distribution. If a sufficient number of sets are subscribed for in 

 advance, this mechanical work will be undertaken by the Library of 

 Congress as a part of its card distriljution work, although the prepara- 

 tion of the index will remain in the Department, Prospective subscrib- 

 ers are requested to communicate promptly with the Department Libra- 

 rian in order to hasten the printing of the cards, and notice will be sent 

 out when the}' are read}' for delivery regarding the proper method of 

 payment. 



While the cost for the complete sets of cards is considerable, it 

 should be borne in mind that the labor of preparing these cards is 

 contributed by the Department Li})rary, and that no private concern 

 would be warranted in attempting the work. The cost of complete 

 sets of cards for the three serial publications noted above is approxi- 

 mately $50, but these sets cover 108 volumes with over 2,500 articles, 

 and include nearly 7,500 cards. Other periodicals are to be taken up 

 later as the work progresses, beginning in each case with the earlier 

 volumes. The value of this index to the investigator will )ie readily 

 appreciated. It constitutes one of those bibliographic helps which no 

 experiment station or large well-equipped agricultural library can 

 afford to l)e without. 



The issuing of a list of current experiment station publications has 

 been commenced by this Office, and the first number has lu'ought 

 many expressions of approval and commendation. The list will be
