To the Editors of the CRIMSON:

During the mid-year and final examinations, it has been the custom at the College Library to allow reserved books to be borrowed from the Reading Room for use overnight, on condition that they be returned by 9 o'clock the next morning. I want to ask those who borrow to take pains to return books promptly, so that other workers may not be deprived of their use.

So far, a number of men have neglected to return their books until noon or later, to the great inconvenience of other students. Unless these is immediate improvement in this respect, I shall be obliged to discontinue altogether the practice of allowing books to be taken out for overnight use, since annoyance to readers the next day exceeds the accommodation to borrowers the night before. Before taking this step, however, I desire to ask the help of all users of the Reading Room toward making the operation of the present method successful. WILLIAM C. LANE,   Librarian.
