OpenStax CNX
American educational website (1999-2022)
Connexions, later known as OpenStax CNX was a global repository of educational content provided by volunteers. The open source platform was provided and maintained by OpenStax, which is based at Rice University. The collection was available free of charge, can be remixed and edited, and was available for download in various digital formats.
Founded in 1999 by Richard Baraniuk, Connexions was based on the philosophy that scholarly and educational content can and should be shared, re-used and recombined, interconnected and continually enriched. As such, it was one of the first Open Educational Resources (OER) initiatives along with projects such as MIT OpenCourseWare and the Public Library of Science. The materials in Connexions are available under a CC BY Creative Commons license, which means that content can be used, adapted, and remixed, as long as attribution is provided. In June 2020, the CNX platform was retired. Its contents remain available on the Wayback Machine.
Subject matter

This brief starts where responsible research should: with the source description of “OpenStax CNX” as american educational website (1999-2022). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as american educational website (1999-2022). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q1126304. 2 of 4 selected statements include explicit references; 3 carry qualifiers and 0 use preferred rank. The first chronological checks are 1999 and 2020.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
