=130.= It is important to note that all fittings which are fixtures, as are most of those about to be described in the following chapter, should be regarded as part of the permanent structure, and not as movable furniture. Such fittings should be included in the loan raised for building, which can be borrowed for thirty years, and not in that raised for furniture, which can only be borrowed for ten years. The additional twenty years for which money can be borrowed for permanent buildings will be found to make a very considerable difference in the annual repayments. =131. Counters and Barriers.=--Counters and barriers are required chiefly in lending and reference libraries, or in situations where it is necessary to cut readers off from books or private rooms. No lending library counter which has to carry an indicator should be more than thirty inches high and eighteen inches wide, and for ledger or card charging and open access the dimensions need not be more than thirty-two inches high and two feet wide. Reference library counters for cutting readers off from the books and for service should be thirty-two inches high and two feet wide. All counters should be fitted on the staff side with shelves and cupboards, and on the public side the panelling should be raised at least four inches from the floor to prevent it from being kicked and marked. It is a useful plan to fit up the back of a long counter with shelves, drawers and cupboards alternately, as shown in diagram on the next page (Fig. 23). This arrangement can be carried out to any extent and in any order, according to space. In lending library counters a slot for money should be made in the top of the counter over one of the small locked drawers. This will form the till for cash receipts from fines, the sale of catalogues, etc. [Illustration: FIG. 23.--Back of Library Counter (Section 131).] =132.= Barriers for open access lending and reference libraries are made in various forms. In small open access libraries the barriers need only be large enough to control the entrances and exits of readers.
