6. Books charged on a Library Use Slip and not returned the same day, when recalled will be treated as overdue and the borrower becomes subject to the prescribed fines. V. Reserved Book Room. Books shelved in this room in order that all students may have an equal opportunity to use them, are restricted as follows: 1. Only one book will be issued at one time, but a dictionary or an atlas will be allowed in addition. 2. A book charged on a white slip must be returned on the day issued or within the time limit indicated if less than one day is allowed. It must not be taken from the building, lent to another reader, or left around the library, but returned and discharged as soon as original borrower can no longer continuously use it. 3. A book may be taken out on a pink slip on the usual overnight conditions. VI. Seminars. 1. Books will be deposited in seminar rooms only at the request of professors or instructors. They will be placed on the shelves in the order of their shelf marks, and should be returned to their places when not in actual use. Such books must not be shut up in the table drawers. At the close of each term all books will be removed from the room excepting those needed during the next term. 2. Books deposited in seminar rooms if needed elsewhere may be withdrawn by library attendants; in such cases the person who requested the deposit will be notified if book is to be away more than one day. 3. Books deposited in seminar rooms are classed as reserved books, and must not be removed from the room where shelved. They may, however, be borrowed overnight subject to the usual procedure and regulations covering such charges. Students must have written permission of the professor or instructor who placed book in seminar to borrow it for longer than over night. All books, whether borrowed by faculty or students, must be regularly charged at the Loan Desk. 4. The use of the seminar rooms is restricted to professors and instructors and to students for whom the privilege has been requested by them. Unauthorized persons must not be admitted by students. Seminar room doors must not be left open, excepting when classes are being held in the rooms. 5. Seminar rooms must be vacated by students when the library is closed. Closing hour week days is 10 P.M.; Sundays and vacation periods, 5 P.M. Students failing to comply with the above seminar regulations are liable to forfeit seminar privileges. VII. Library Fines and Penalties. Fines on overdue books are not for the purpose of revenue. Indeed, they do not accrue to the funds of the library, but they have been proved necessary to obtain observance of the regulations made to protect the rights of all readers.
