(6) That the index of veterinary literature now maintained in the Bureau 

 of Animal Industry be transferred to the department Library and the force at 

 present engaged thereon be placed under the jurisdiction and supervision of 

 the librarian of the department. 



(7) That, in so far as practicable, bibliographical work and indexing (other 

 than the indexing of department publications) be done by the Library of the 

 department. 



(8) That all exchanges received in return for department publications be 

 regarded as the property of the main Library and be sent there to be catalogued. 

 If required by the bureaus later, such exchanges received could be loaned in the 

 usual manner. 



APPENDIX 3. 



CIRCULATION OF CURRENT PERIODICALS— RULES AND SUG- 

 GESTIONS. 



(1) Periodicals should be glanced over as soon as received, in order to ascer- 

 tain whether or not the numbers contain any items of interest. If they contain 

 nothing of interest, they should be returned immediately to the library from 

 which they were borrowed. 



(2) No number of a periodical in regular circulation should be kept more 

 than three days. 



(3) Periodicals must not be passed from one person to another without noti- 

 fying the library from which they were borrowed, in order that the charge 

 record may be changed. Persons to whom the periodicals are charged are held 

 responsible for them. 



(4) Numbers containing continued articles should not be held awaiting the 

 receipt of the concluding article. When the number containing the conclusion 

 of the article is received, the previous numbers may then be requested. 



(5) Persons to whom periodicals are sent regularly are requested to notify 

 the library when leaving the city for more than three days, in order that the 

 current numbers may not accumulate in their offices during their absence. 



(6) Persons receiving periodicals regularly are requested to go over their 

 lists carefully for the purpose of eliminating any periodicals which contain 

 little or no material of interest in their work. In the case of those which are 

 requested for a limited length of time while special work is being carried on, 

 the library should be notified when the work is completed, in order that the 

 sending of these periodicals may be discontinued. The work of circulating 

 current periodicals is very heavy and the regular circulation should be strictly 

 limited to those of real importance in the various lines of investigation being 

 carried on by the department. In this connection attention is called to the 

 fact that the main Library maintains a periodical reading room (room 30), 

 where the current files of about 800 periodicals may be consulted. 



APPENDIX 4. 



RULES FOR INTERLIBRARY LOANS, 



Attention is called to the following rules of this library in regard to inter- 

 library loans. A strict observiince of these rules on the part of librarians and 

 scientists and a critical elimination of all unimportant and unnecessary requests 

 will greatly facilitate the work and lessen the expense and risk involved in 

 such loans. 



(1) Books are lent to other libraries for the use of investigators engaged in 

 serious research, in cases where such lending will not interfere with the work 

 of the department. The material lent can not include books in frequent use 

 in the department; books that should be in the local library; textbook? or 

 popular manuals; nor books for use in ordinary student or thesis work. 



(2) Unless otherwise syecitied, books are lent for one month, including time 

 en route.
