=308.= Maps do not fit readily into the vertical system, and are troublesome material as a rule. Several solutions of the map-filing problem have been suggested--rolling them and inserting them in tubes in a cabinet on the principle of the umbrella stand; mounting them on spring rollers and fixing them over bookcases where they can be drawn down to be consulted exactly as a blind is drawn; and an ingenious method devised by Mr G. T. Shaw, and described in _Public Libraries: their Organization, etc._, 1918 (Library Association), is worth examination. For the many small maps that all libraries possess, flat filing in such boxes as Fig. 118 depicts is probably the best. Single sheets of the Ordnance Survey, or other similar maps which are much handled, should be mounted on linen or some similar material, and an additional protection from tearing is to bind them with tape, which may be done by folding the tape over the edges and running them round with an ordinary sewing machine. [Illustration: FIG. 118.--Box for Filing Prints and Maps (Section 308).] =309. Newspaper Clippings.=--The vertical file is an excellent instrument for dealing with newspaper clippings. These, in the case of matters of temporary interest, may be dropped into classified folders. For clippings which it is desired to keep, it is better to provide a mount, which may be of paper of sufficient substance to bear them, and paste them down, writing in the top left corner the class-number, subject, source and date of the clipping. The older methods of filing clippings in newspaper-cuttings books, or in any form of guard book, have the disadvantage of inflexibility, want of rational means of indexing the contents, and occasion reference in course of time to several volumes for matter on any subject. =310. General.=--For most filing purposes quarto folders, to accommodate quarto papers, which file in standard-sized drawers, are sufficient; but both drawers and folders can be obtained in foolscap and other sizes. And notwithstanding our advocacy of the loose method of filing, there is much to be said for such files as the Stolzenberg for papers which have an invariable chronological appearing and are valuable in that order; because the file, having the apparatus already described for securing and binding the papers, has the never-to-be-discounted virtue of book form. Such papers are minutes, periodical reports on special departments, financial analyses, book-lists, etc. Moreover, although the standard Stolzenberg cabinet accommodates its folders in horizontal fashion, the latter are also suitable for filing vertically in the drawers recommended for general purposes.
