Edition and citation
The printed book is the durable scholarly edition. When citing the book, use the edition and bibliographic information printed in that edition. When citing a companion page, include the page title and an access date where your citation style calls for one.
Corrections
Material errors should be corrected rather than silently defended. Significant corrections to the book or companion will be identified here when they affect interpretation, teaching, or citation.
Online companion material
Companion resources may be revised between print editions as methods, examples, teaching materials, or tools improve. Where a change materially affects how a resource should be interpreted or cited, the relevant edition or revision should be identified on that resource.
AI-assisted editorial work
Artificial intelligence may assist research organization, comparison, critique, drafting support, and editing. AI output is not treated as evidence merely because it is fluent. Source verification, substantive judgment, and authorial responsibility remain human.
Technical documentation
Repository structure, build processes, deployment details, and other implementation notes belong in project documentation rather than the normal reader experience unless they directly affect how a reader uses or cites a resource.
