Dummies and Overflow Stock.=--Sometimes the library becomes congested at certain places owing to limited space and rapid growth, and if discarding is not resorted to some of the less popular, or old, books must be removed to a supplementary store. There is scarcely a library which does not possess a second classification stored apart, where such crowded-out books are kept. On the shelf-register these books can either be indicated by some such means as a red-ink cross, or they can be removed from the original and entered on supplementary sheets. Dummies, such as those described in Section 247, can also be used to show books located elsewhere, especially in open access libraries, or lists can be mounted on cards and kept beside each tier. The question of surplus stock is one which ought to be dealt with on the broad lines of the discarding policy discussed in Section 199, but, of course, an actual division of stock caused by overcrowding must be treated as recommended above. Large and odd-sized books should be shelved in special presses, and their place in the classification can be indicated by means of dummies, as described below. [Illustration: FIG. 82.--Shelf Dummy for Book Shelved out of Order (Section 247).] =247. Shelf Accessories.=--For the purpose of maintaining order on the shelves and marking particular divisions or classes, various devices have from time to time been introduced. DUMMIES are used to indicate the temporary absence of books, or to show that particular works, because of their large size, are located on some other shelf. The simplest form of shelf dummy for classification purposes is a block of wood about 7 inches × 5 inches × ⅝ inch, painted white, or covered with white paper on the edge, and lettered with the title of the book which it represents. The title may be written on each of the seven-inch faces, in case the block gets reversed, and should also bear a plain direction to the location of the book it represents (Fig. 82). [A similar dummy, bearing the classification number and the name of the division, serves as a good guide to the classification. The block is inserted at the beginning of each new classification sequence; and both in this case, as in that of the dummy that represents books, the dummy is too unlike a book to be taken for anything other than a guide.]
