ETIS Library

A guide to ETIS books, editions, publication series, formats, downloads, and educational products

The ETIS Library helps readers understand the ETIS book architecture, published editions, focused publication series, downloads, and educational products, and choose the form best suited to their work.

ETIS is not a single file or book. It is an integrated engineering knowledge ecosystem delivered through:

  • the authoritative website;
  • the complete online ETIS Framework Reference Work;
  • the ETIS Two-Volume Professional Edition;
  • the ETIS Professional Computing Series;
  • three coordinated focused publication series;
  • educational products;
  • downloadable offline editions;
  • public repositories and the Engineering Platform.

These are complementary access paths into one coherent body of work.

The distinction is intentional:

  • Books provide sustained professional works. The ETIS Framework Reference Work defines the complete framework; the Professional Computing Series develops focused, transferable engineering judgment.
  • Publications are focused works with canonical landing pages, metadata, citation, version history, related materials, and authoritative PDFs.
  • Downloads are curated offline products such as authorized book PDFs, guides, educational packages, and repository archives.
  • The Library explains the available formats and helps readers select the right one.

Website Edition

The ETIS website is the primary public platform for the framework and the canonical online home for the broader ETIS publishing ecosystem.

It provides:

  • the complete online ETIS Framework Reference Work;
  • the full lifecycle structure;
  • appendices;
  • framework references;
  • the Publications Program;
  • educational resources;
  • downloads;
  • repository guidance;
  • continuing ecosystem updates.

For Professional Computing Series titles, the website provides the canonical book record, authorized downloads, companion resources, updates, errata, and print-edition purchase links.

New public ETIS resources should appear on the website first.

ETIS Books

ETIS books now serve two complementary publishing roles.

ETIS Framework Reference Work

Engineering Trustworthy Intelligent Systems: Software Engineering, Governance, and Operational Trust in the AI Era is the definitive ETIS framework reference. It defines the complete lifecycle discipline across software engineering, AI-assisted development, governance, operations, oversight, and stewardship.

For print publication, the Framework Reference Work is organized as the ETIS Two-Volume Professional Edition. Authorized PDF access is available both as the complete First Edition and as individual volume editions.

ETIS Professional Computing Series

The ETIS Professional Computing Series develops durable professional judgment through focused computing books aligned with the broader ETIS philosophy.

The inaugural title is:

From Data Structures to Engineering Judgment
Engineering Trustworthy Intelligent Systems in the AI Era
William T. O'Connell, Ph.D.

The book uses data structures and algorithms as a vehicle for developing engineering judgment about representation, prediction, evidence, tradeoffs, scale, policy, system consequences, AI-assisted engineering, and professional responsibility.

The ETIS website provides a free PDF edition, companion resources, and the canonical publication record. Print editions are available through Amazon.

Published: August 2026 · First Edition
Paperback ISBN: 979-8-9966760-4-0
Hardcover ISBN: 979-8-9966760-5-7

Each publication has:

  • a canonical webpage;
  • title, series, identifier, date, version, and status metadata;
  • an executive or core thesis;
  • a concise summary and intended audience;
  • related ETIS resources;
  • standard citation formats;
  • version history;
  • access to the authoritative PDF edition.

First Edition

The First Edition of Engineering Trustworthy Intelligent Systems: Software Engineering, Governance, and Operational Trust in the AI Era establishes the foundation of ETIS.

It defines the core doctrines:

  • AI proposes; engineers verify;
  • governance is architecture;
  • context is control;
  • everything important leaves evidence;
  • the model is not the system;
  • a demo is not operational proof.

Two-Volume Professional Edition

The two-volume edition improves readability and physical usability while preserving ETIS as one integrated framework.

The volumes are not separate works. They are two movements in one professional engineering journey.

Explore the ETIS Two-Volume Edition →

Volume I

Foundations, Engineering Practices, and System Construction

Volume I addresses how intelligent systems are framed, designed, constructed, verified, reviewed, and defended for release.

Explore Volume I →

Volume II

Operations, Governance, Oversight, and Stewardship

Volume II addresses how intelligent systems are operated, governed, observed, secured, improved, overseen, and stewarded over time.

Educational Products

The ETIS Educational Ecosystem translates the framework into teaching, learning, course-operation, and institutional-adoption resources.

Educational products include:

  • ETIS Educational Ecosystem Guide;
  • ETIS Instructor Course Package;
  • ETIS Classroom Facilitation Guide;
  • ETIS Instructor Handbook;
  • ETIS Student Professional Engineering Guide;
  • ETIS COMP 330 Flagship Implementation Guide.

These products are implementation and adoption resources. They are distinct from the ETIS Education Paper Series, which provides focused professional readings.

The Educational Ecosystem is also supported by complementary educational engineering tooling. These tools extend ETIS educational products by helping students strengthen repository quality and assisting instructors with evidence-centered repository evaluation throughout the engineering lifecycle.

Repository and Engineering Platform Resources

ETIS is intentionally repository-centered.

The public repositories preserve source, reusable artifacts, decisions, governance records, and engineering examples. The Engineering Platform provides the working implementation layer.

Repository and platform resources support:

  • evidence-centered engineering;
  • governance traceability;
  • instructional use;
  • project startup;
  • professional adoption;
  • reference implementations;
  • long-term stewardship.

Versioning Philosophy

ETIS values stability, traceability, and continuity.

  • Minor corrections may be published through errata or website updates.
  • Publication revisions should preserve version history.
  • Substantive doctrinal changes should be reserved for future book editions.
  • Future editions may expand ETIS while maintaining continuity with the foundational principles of the First Edition.

ETIS is designed to evolve without becoming unstable.
