 collections, and in the work of publication. In this library shall be 

 kept all books, pamphlets, journals, maps, &c., and such of the archives 

 of the Museum as may be there assigned.

 than one subject, such as ijeriodicals, proceedings of societies, serial re- 

 ports, dictionaries, and cyclopedias, together with such monographs as 

 are not desired in the Sectional Libraries. To each Sectional Library 

 which may be formed, only those works may be assigned which relate 

 directly to the work of that section only. Books in Sectional Libraries 

 shall be considered to be personally loaned to the Curators in charge. 



ENTRIES OF BOOKS, ETC.
