Appendix F — Further Reading
This list gives the primary sources behind the book: every source in the chapters’ research boxes, and the main papers, cards, write-ups, frameworks and documentation the chapters discuss in their text. There are no news stories, summaries or secondary blogs. Every entry was checked against this book’s source notes, and every link is the one recorded there, as of October 2026.
By Part, then by chapter. Each source appears once, under the first chapter that discusses it; a note says where else it appears. Each entry gives the authors, the year, the title, the venue or arXiv number, the link, and one line on why to read it.
(abstract) means this book’s notes checked only the abstract or the official summary, so the book’s claims about that source go no further than the abstract. Reading the full text is the next step.
For studies that made a model misbehave on purpose (Part VII especially), the list links the papers and posts only: no datasets, scenario code or model weights. Papers about attacks are listed for what they measured and what defends against them. The book reproduces no attack material, and neither does this list.
