A projecting brass rail, upon which readers may rest their arms, should always be fixed at the bottom of the slope. About _4_ feet run should be allowed for each paper when possible, but _3_ feet _6_ inches will do if space is limited. The usual height of wall slopes is _3_ feet, from the floor to the bottom of the slope, and _5_ feet from the floor to the title plate, which should take the form of movable boards fitted into brass brackets and placed at the top of the slope in the centre of the newspaper. The bottom of the slope should be _1_ foot _3_ inches from the wall. There are several kinds of brass screw clips for fastening the newspapers to the stands, but revolving holders should be used for illustrated papers. READING ROOM CHAIRS. Arm-chairs are to be preferred to any others. The height of the seat should be _1_ foot _4_ inches except for juvenile readers (when the height will range from _12_ inches for children _5-9_ years of age, with an additional inch for every four years up to _21_ years of age). “OPEN-ACCESS” ENCLOSURE. The lending library counter in an open-access library should be _3_ feet high and _2_ feet wide and the minimum area for the enclosure should be _8_ feet by _8_ feet for the smaller libraries and a minimum of _10_ feet by _10_ feet for libraries registering a daily issue of over _1,000_ volumes. For detailed kinds of barriers, latches, etc., see Brown’s “Manual of library economy,” _1907_ edition, Sections _128-129_; _1919_ edition, Sections _131-136_; and Brown _and others_ “Open-access libraries.” MISCELLANEOUS. Gangways between double reading tables, with movable chairs should be at least _6_ feet. Gangways down the sides of centre of a room should be _7_ feet. Space between each book, stack in a closed library should be a minimum of _4_ feet and in an open-access library a minimum of _6_ feet. In planning buildings _18_ to _24_ inches should be allowed for external walls, and _6_ to _9_ inches for internal walls. COURSE 7: LIBRARY ADMINISTRATION. TEXT BOOKS REQUIRED.
