	Termatrex was an optical coincidence index system, also known as a feature card system. Instead of a record for each document with index terms attached, a record was created for each attribute (index term for topic, creator, etc., with the ID for each document assigned that attribute.

			Adding an removing cards in varying order allowed heuristic search strategies. Various elaborations and ancillary equipment were developed to ease large scale operation, including a counter that reported the number of light spots generated by each search.

			The Minimatrex, introduced in 1963, substituted microfilm frames, half an inch by half an inch, each corresponding to a 10,000 position card. Each frame was on a separate strip of film. Frames were phtpgraphs of existing cards or could be computer generated, Ten frames could be superimposed to scale up to handling 100,000 documents. Great precision was required to make the microfilm frames, but, once made, copies of the filmstrips and readers could be duplicated and distributed at low cost.

			A pilot "Project Law Search", using Minimatrex equipment, was supported by the Council on Library Resources.
