examples of how this has been done on four sites of different shapes and areas.
Opinions are divided upon the question of supplying free sanitary and lavatory accommodation for readers. If the library is large, and can afford to engage an attendant, they are most useful adjuncts; but if they have to be left open without supervision, they will prove a nuisance in more senses than one. The provision of a lavatory for hand-washing only is almost necessary for reference libraries, and will repay itself in the better condition in which the books are maintained. A certain amount of dust seems inseparable from the reference department, and it is well to give the scrupulous reader an opportunity to remove it.
