5. Cross gangways between table and bookcase-ends should not be less than 3 feet if used as thoroughfares, but may be 2 feet only if simply spaces to enable readers or assistants to pass round. 6. Bookcases should not exceed 7 feet 6 inches in height either in open access or closed libraries, and shelves should be of the uniform length of 3 feet, unless for folio and quarto stock, when 18 inches will be found better. For fiction wall shelves in open access libraries, the depth should not exceed 7 inches. 7. Standard bookcases in open access libraries should be spaced at not less than 6 feet apart when facing each other, and in closed libraries at not less than 3 feet apart. 8. Magazine room readers should be allowed not less than 12 superficial feet each, including table and passage room. 9. Reference library readers should be allowed not less than 18 superficial feet, including table and passage room. 10. Where indicators are used in lending libraries the counter space should provide 5 feet run for every 4000 volumes stored, or 15 inches per 1000 numbers, and at least 10 feet run of clear space for service. The public space in front of any such counter should not be less than 10 feet wide, unless in a very small library, when it may be 6. 11. In open access lending libraries the spaces should not be less than those shown in No. 7 above. As a general rule it will be found easy and fairly accurate to allow 20 square feet to every borrower estimated to be present at one time, and disregard the provision of stock. In this calculation allowance is made for gangways, stock and readers. 12. Allow nine volumes per foot run in lending library shelving, and eight volumes per foot run in reference library shelving. A 7 foot 6 inch bookcase should give an average of eight shelves per tier in a lending library, and about the same in a reference library, if separate provision is made in wall cases for folio and other large books. 13. Public lobbies and staircases must be arranged according to the rules laid down by any local or general building act or bye-law. 14. Newspaper slopes should allow an average of 4 feet run for every paper. This will provide for spaces between papers. In some towns the competition designs for library buildings have been placed on exhibition, to enable the public and other interested persons to compare the premiated with the other drawings. This seems an admirable procedure, regarded as a mere matter of policy, but the practical advantage is somewhat doubtful.
