of the two systems. Fig. 4 is the plan of a library arranged with alcoves, and Fig. 5 the plan of the same room divided into book store and reading-rooms, and arranged upon the stack system.
An examination of these two plans will show that in each case there is practically the same area available for readers, while the shelf capacity of Fig. 5 is quite double that of Fig. 4. If the alcove system is used for public libraries, it is necessary to have locked doors to the cases, and the greater distance for the attendants to go to obtain the books inquired for, combined with the delay caused by locking and unlocking the doors, materially affect the service. There is also much discomfort to the readers who go into an alcove to be out of the way, and have their attention distracted by the passing to and fro of the attendants. Supervision of the tables in the alcoves from the catalogue counter is impossible, and opportunities for theft and mutilation of books are provided, without much chance of discovery. The initial cost for shelving in the alcove system is greater than in the other, for it is generally necessary to provide bookcases for the whole room at the inception, while in the second plan they can be added as required, until the room is filled.[1] In Fig. 5 no doors are required for the bookcases as a protection from theft, and as they are out of sight, they can be built without ornament, and of the plainest materials consistent with durability and neatness.
