SirsiDynix
software company
SirsiDynix is a United States company that produces integrated library system (ILS) software and associated services for libraries.
Origins
The Sirsi Corporation was founded in Huntsville, Alabama in 1979 by Mike Murdock, Jacky Young, and Jim Young. The Unicorn library automation system they developed was first installed at Georgia Tech. Sirsi acquired Data Research Associates (DRA) for $51.5 million in 2001.
The Dynix Corporation was founded in 1983. Their major product was the Dynix Automated Library System.
In January 1992, Dynix Systems was acquired by Ameritech. Dynix and NOTIS Systems (maker of NOTIS), which Ameritech purchased in October 1991, were consolidated into Ameritech Library Services (ALS) in 1994.
In November 1999, Ameritech sold Ameritech Library Systems to a pair of investment companies, the 21st Century Group and Green Leaf Ridge Company, which rebranded ALS as epixtech. In 2003, epixtech reverted to using the Dynix name.

Why this record matters
“SirsiDynix” is worth following because a concise public description often conceals a longer documentary argument. Here, SirsiDynix, software and company provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 5, 2026. The linked authority identifier is Q3485305. Authority coordinates are 40.429, -111.893. 2 of 4 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1979, 2001, 1983 and 1992.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
