Engravings are best filed in a cut cabinet of the usual style. This is a cabinet of shallow drawers, just deep enough to hold type-high cuts. All engravings should be numbered and electrotypes stamped with the same numbers as the originals. The cuts can then be filed by numbers, and each drawer labeled to show the numbers of the cuts it contains. [Illustration: Fig. 4. Loose-leaf Scrap Book Sheet for Preserving Proofs of Engravings] Cuts should be numbered consecutively, and when an engraving is made in a new size it will take the next number, regardless of the fact that an engraving of the same design has already been made. For instance, if five sizes of engravings are made from one design, there will be five cut numbers. When the cut is numbered, it is a good plan to stamp the number on the back of the design; then reference to the design will show how many times it has been engraved and the numbers of the cuts. Proofs of all engravings should be kept. These may be pasted in scrapbooks, but the books should be loose leaf. This makes it possible to eliminate all dead matter; when designs are of no further use, the sheets containing the proofs can be destroyed. A sheet may contain proofs of one or of several cuts, depending on the size, but all proofs should be arranged in numerical sequence. The sheet should also show the cut number, the subject, and the date of ordering electrotypes, as shown in Fig. 4. Since the space required for proofs cannot be told in advance, it is more practical to substitute a rubber stamp impression for printing. By using a small stamp, this information can be stamped opposite each proof. [Illustration: Fig. 5. Index Card for a Record of Designs and Engravings] =Cut Indexes and Tracers.= To complete the filing system for cuts and designs, an index is needed. Fig. 5 shows a convenient form of index and record card. This card is headed with the name or subject of the design, and is indexed under this subject. The data relative to the design includes the class--as photograph, wash drawing, or line drawing--the name of the artist, the size of the design, and the date made. Below this is a complete record of all original engravings and electrotypes made from the design, including their numbers. On the back of the card is a record of the publications, catalogs, or circulars in which the design is used, with dates, as shown in Fig. 6. If the name of the artist who made a certain design, or the names of publications in which it has been used, is wanted, reference to this card gives the desired information. This one card provides all information that is likely to be needed in reference to both designs and engravings. [Illustration: Fig. 6. Reverse of Index Card Showing Where Engravings are Used]
