The building should be planned with a view to economical administration.
The rooms for public use should be so arranged as to allow complete supervision with the fewest possible attendants.
There should be throughout as much natural light as possible.
Windows should extend up to the ceiling, to light thoroughly the upper part of every room.
Windows in a book room should be placed opposite the intervals between bookcases.
In a circulating library the books most in use should be shelved in floor cases close to the delivery desk.
A space of at least five feet should be left between floor cases. (If the public is excluded, three feet is ample.)
No shelf, in any form of bookcase, should be higher than a person of moderate height can reach without a stepladder.
[Shelving for folios and quartos should be provided in every book room.]
Straight flights are preferable to circular stairs.
