Abstract:

The Nondestructive Testing Information Center uses the Termatrex system of coordinate indexing to identify and retrieve desired abstract cards and documents in their collection. The system uses visual coincidence peak-a- boo term cards in which holes are drilled in specific locations to represent documents possessing a particular term. Documents identified by a group of desired terms may be retrieved by superimposing the term cards and observing the resulting coincident holes. The present set of cards is capable of handling up to 10,000 documents. Expansion beyond this capacity requires an additional deck of term cards that must be processed and searched separately. Since the Termatrex system is an economical, rapid retrieval system that fills the Centers needs, no plans have been made for the application of computer techniques.
