Linick, Evan,

The MARK IV User Group, officially "MARK IV User Group (IV League)," purpose was to advance effective use of the MARK IV System. The group's 1969 by-laws described the MARK IV System as "a proprietary software product (which included program, documentation, and system support) developed and owned by Informatics Inc." and a presentation outlines the MARK IV System more specifically as "a general purpose software package designed to aid file management activities." Members included Informatics and representatives from any MARK IV installation.
