=112.= This chapter is of a purely practical character, with illustrations from well-known examples of library plans. Except in the necessary precautionary remarks made already, it has been thought undesirable to dwell upon the elevations of libraries and the relative desirability of façades, although much might be said upon the subject and it is worthy of careful attention. Such a discussion, however, could be useful only if a long series of illustrations were given ranging say from the New York and Pittsburgh public libraries, the National Library of Wales, the Liverpool Public Library and the Mitchell Library at Glasgow, which are large and handsome architectural edifices, to the more modest but satisfactory small buildings such as those at Bromley, Herne Hill and Wallasey. Although a certain common character is to be found in smaller municipal library elevations, and especially in Carnegie libraries, there is no distinctive type of elevation peculiar to libraries which immediately suggests the purpose of the buildings. This is one of the things to be desired in British architecture, as it is fair to expect that such buildings should be both artistic and appropriate, if such results can be reached without the sacrifice of even more important considerations. =113.= It is premised that all central libraries require certain departments, including reference and lending libraries, newspaper room, magazine (or periodicals) room, children’s room, lecture room, and administrative departments--librarian’s office, cataloguing room, store rooms, staff rooms, cloak rooms, etc. Too often the provision made for administrative and staff purposes is inadequate, and the library suffers greatly in consequence. Branch libraries do not, as a rule, have reference rooms, although accommodation for a collection of quick-reference books is necessary, and in many branch libraries newspaper and magazine rooms are combined. All the apartments premised above are not present in all buildings. Older libraries have no separate provision for children, and indeed work with children on a large scale is quite a recent development of library activity, but the desirability of such a department is made clear in Division XIII. Lecture rooms are rarer still, because of the peculiar view taken by legal authority that lectures are not within the province of libraries; and in some of the larger cities lecture work is adequately carried out by other institutions. A modern librarian, however, regards a lecture room as a necessary part of his building, and even in the larger cities lectures which are purely library lectures, having a direct bearing upon the use of books, can be given satisfactorily only in direct connexion with the library. =114. Sites.=--In choosing sites for public library buildings committees should bear in mind the following principles:-- 1. They should be central and easily accessible from all parts of the district, by tramways or other conveyances.
