Release 0.22 · 5 September 2026
A clearer entrance to systems thinking, more ways through the early cybernetics literature, and the RedQuadrant rules ready for use elsewhere.
The new systems-thinking introduction begins with recurring problems, follows a waiting-list example, and offers a ten-minute inquiry. It introduces the fields and gives routes into methods, reading, and communities of practice.
It is designed as the educational entrance for systemsthinking.info. Its content works without JavaScript, with readable type, keyboard links, responsive layouts, and a print treatment.
The historical collection retains all 48 supplied entries from Wiener’s reading lists. You can search, filter by source section or review depth, follow atlas links, and download the catalogue.
Sean Manion, @TheUnjournaling, is credited for sharing the historical material. The original compilers, publication authors, and Systems Community of Inquiry transcriptions retain their separate credits.
New accounts cover communication questions, information coding, ultrastability, and essential variables, with practice questions distinguished from historical claims.
The random RedQuadrant rule has been removed from the atlas header. The complete set of 256 rules remains available, including individual links and a random-rule control.
Exact texts and reusable code are ready for a discreet strip above the RedQuadrant footer, connected to the Tool Shed, and a practice aside beside the writing and library material on antlerboy.com.
The atlas now contains 719 canonical public entries, up from 635; 137 developed profiles, up from 128; 224 source records; 1,987 typed statements; and 24 journeys.
The 48 historical source rows resolve to 45 distinct works and one unidentified issue reference. Two works occur in more than one list. Four selected primary-passage reviews and one archive metadata check deepen this intake. Most of the listed works remain at bibliographic-record depth.
The Barrett–Shepard source supplies its three-page introduction and six categories, but none of the bibliography’s hundreds of entries. Those missing pages are still needed. A list described as 1956 includes a 1957 publication; that discrepancy remains visible.
The approved Systemic Evolution map retains its exact reviewed dataset and source-permission boundary. A title’s inclusion in a bibliography is recorded as a documentary connection, with no invented claim of influence.
Benjamin P Taylor has authorised direct publication of requested site changes after validation. The repository instructions now reflect that, while retaining source rights, evidence distinctions, and access controls.
The release checks cover data integrity, source accounting, all 256 rule texts, new static routes, preserved map checksums, and the behaviour of the filters and rule controls. These checks do not constitute a full accessibility audit.
