4. Files. As has already been stated, the style of file, as well as the method of filing, or indexing, must conform to the conditions in each individual office. However, the experience of the past is the best guide for the future. As a general rule, sectional bookcases will be found the most satisfactory for catalogues in bound form, that is, those with substantial covers, and particularly those that will readily stand on edge. An advantage of the sectional bookcase is that all catalogues can plainly be seen, and even though a numerical system be used, a man soon learns to recognize catalogues of certain manufacturers without referring to any number or indexing system.
In every catalogue file will be found pamphlets, circulars, and price lists which are not easily cared for in bookcases. For these a section of a vertical file is recommended, and in many cases this file has been used successfully for filing all sorts of miscellaneous catalogues. It may be expanded to any capacity, and can be used with equal success for either the alphabetical or numerical system of indexing.
Which is the better depends upon the circumstances, but in nearly every case either the sectional bookcase or the vertical file, or perhaps a combination of the two, will be found most satisfactory.
5. Catalogue Indexing. The principal value of a file of catalogues lies in the index. A miscellaneous lot of catalogues is of very little value unless it be properly indexed. True, most catalogues contain an index, but this is not the sort of index required by the purchasing agent. He does not care for an itemized list of every article manufactured by John Jones & Co., but he does want an index that will show him where he can find descriptions and prices of machines of a certain class. A catalogue may list thousands of articles in which the purchasing agent has no interest, where it lists ten that are of use to him. These ten articles are the ones which should be shown in his index.
Fig. 1. Subject Card for Catalogue Index
The principal index of the catalogue file is one arranged by subjects. A card used for this purpose is shown in Fig. 1. At the top of the card is listed the subject. Below this is given the names and addresses of all manufacturers supplying the goods listed. In the columns at the right are recorded the section number, catalogue number, and page. The section number refers to the section in the file where the catalogue will be found; the catalogue number to the catalogue itself; and the page to the number of the page in the catalogue. In making up such an index, it is unnecessary to include a long list of articles of no especial interest, but simply those which the concern is obliged to purchase. If an entirely new subject comes up, it can then be listed after suitable investigation.
These cards are filed alphabetically, according to the name of the subject. While in some large concerns a more elaborate file will be necessary, this index can usually be kept in a small card tray in a desk drawer.
