REGULATIONS 



The library is open to the public every day, excepting Sundays, 

 from 9 a. m. to lo p. m. 



Books shelved in the Reading Room may be consulted without 

 formality, but after use are to be left on the tables, instead of being 

 replaced on the shelves. 



Current periodicals may be consulted within the periodical alcove; 

 and may be obtained for use at the tables in the Reading Room by 

 presenting to the Periodical Cleric a serial call-slip properly filled out. 



Books not shelved in the Reading Room may be obtained by pre- 

 senting to the Delivery Clerk a book call-slip properly filled out. 

 These books are to be returned to the delivery desk. 



Persons engaged in special research, if satisfactorily vouched for, 

 may be admitted to the Stack Room. All books used under this 

 provision are to be left on the tables in the Stack Room. 



Books of great value and rarity may be consulted only in the 

 presence of an attendant. 



Writing or marking in books belonging to the library, or their 

 mutilation in any manner, is forbidden. The tracing of plans will be 

 permitted if done over a celluloid cover, but not otherwise. These 

 covers will be furnished upon application at the delivery desk. 



A printed card catalogue has been prepared for the use of the 

 public. It is in three sections, alphabetical author, alphabetical sub- 

 ject, and classed subject. 



The Reference Librarian, in charge of the Reading Room, will 

 give assistance in the use of the catalogue and the selection of books.
