5-foot high,136-drawer pre-computer manual storage system for finding books and other materials at a library. Has rod screw in bottom of each drawer, used to hold the cards in the drawer, which are held in place to keep from falling out by a bottom hole similar to the grab points on a Rolodex card. This catalog would typically contain hundreds of cards in each drawer, each representing one book, map, record, movie or other item. Some libraries continue to maintain the paper card catalog as a backup, but the enormously reduced labor and cost to use a computer-based catalog instead of a manually organized card file, has caused most libraries to discontinue paper-based card catalogs. But, if you're doing a pre-1980 library it will have card catalogs like this. This particular case could have held about 65,000 records allowing space for examining cards and inserting new or replacement ones. The main downtown branch of the Los Angeles Public Library, for example, which had about 2 1/2 million items before the two fires, would have had about 40 of these in the main search room, for that one branch alone. There are two smaller versions of this model, one with 128 drawers and support shelves for resting removed drawers, and a 4-foot high one that has 48 drawers, holding about 20,000 records.
