Abstract
A collective objects management system for objects such as documents contained in file folders in drawers of file cabinets. Each file folder has an electrical circuit with a visible indicator mounted on the file folder. Each folder circuit has a pair of crystals which are responsive to R.F. signals of specific frequencies, the frequencies of each pair being different for each folder circuit. An associated computer operates an R.F. signal generator to produce R.F. signals at the frequencies of the particular folder circuit of the file folder selected for retrieval. To aid the user, each file drawer has a visible indicator mounted on the front panel, the panel indicator being illuminated when the sought folder is contained in that drawer. The invention can be applied to a wide variety of collective objects management systems, such as supermarkets, automobile parts distributors, and various manufacturing operations.
