GRIPHOS (General Retrieval and Information Processor for Humanities Oriented Studies) is a historically important suite of programs used extensively within the Museum Computer Network, a shared information management system developed jointly by fifteen New York area museums. Designed by Dr. Jack Heller of New York University's Institute for Computer Research in the Humanities (ICRH) and debuting in 1967, GRIPHOS enabled museums to store, retrieve and apply textual markup to their records.
