The Dynix Automated Library System was a popular integrated library system, with a heyday from the mid-1980s to the late-1990s. It was used by libraries to replace the paper-based card catalog, and track lending of materials from the library to patrons.[2]
First developed in 1983, it eventually became the most popular library automation software ever released, and was once near-ubiquitous in libraries boasting an electronic card catalog, peaking at over 5,000 installations worldwide in the late 1990s, with a market share of nearly 80%,[3] including the United States' Library of Congress.
Typical of 1980s software technology, Dynix had a character-based user interface, involving no graphics except ASCII art/ANSI art boxes.
