82 REPORT OF THE SECRETARY. 



15. It shall be the duty of the librarian at all times to hold these books, in classes 

 '' C '" and " G," open to the inspection of the Librarian of Congress, and to report 

 to him the place and condition of any work under his charge in answer to any specific 

 inquiry. 



16. In addition to the books wliich are included in the Smithsonian deposit in the 

 Library of Congress, and so stamped, there are certain books procured by the 

 Smithsonian Institution for use in the National Museum. These shall be distinct- 

 ively marked, and it is understood that, while they form no part of the above- 

 described books of the Smithsonian deposit in the Library of Congress, they are iu 

 other respects to be treated iu accordance with the above regulations. No book or 

 chart belonging to the Smithsonian Institution is exempt from them unless procured 

 for the specific use of the Secretary, Assistant Secretary, or assistant in charge of 

 the Smithsonian, as above designated, and distinctly stamped as belonging to his 

 oiiice. Under this clause come books ptirchased especially for the office of' the 

 Secretary, Assistant Secretary, or assistant in charge, forming ''ofiSce libraries." 

 Indispensable books of reference in exchange departments, etc., form jiart of the 

 Chief Clerk's oflicc library. 



This is to be understood as including the books purchased at the expense of the 

 Museum appropriation, but not necessarily the books obtained by exchange for 

 Museum publications, as it would be difficult, if not impossible, always to discrimi- 

 nate these under our present system. This point is reserved for future consideration, 

 but provisionally it is understood that the librarian is to send books to the Library 

 of Congress, if not evidently meant for the Museum. 



The books ^n-ovided for the. office of the Secretary, and stamped " Secretary's 

 library," are a distinct class, having no relation to the Library of Congress or to the 

 sectional libraries. They may be lent on application iu special cases by the Assist- 

 ant Secretary or assistant in charge through the librarian. All other books (not 

 forming a portion of the Smithsonian deposit with the Library of Congress, but 

 belonging to the Institution) are stamped "Office library," which includes editor's 

 library. Chief Clerk's office library, and others, and these, as well as those of the 

 Secretary's library, are in the charge of the librarian. 



Respectfully submitted. 



Cyrus Adler, Lihrarian. 



Mr. S. P. Langley, 



Secretary of the Smithsonian Institution.
