Every course here is written against a named anchor text — one standard work whose terminology and topic boundaries the course follows — and checked against a secondary witness written independently of it. Where the two disagree, the course follows the anchor and says so at the entry where the disagreement lands. These are the texts for American Government.
- Anchor
-
OpenStax, American Government 4e (Krutz & Waskiewicz). Pinned to the live web edition dated April 23, 2026.
- Secondary witness
-
Lenz & Holman, American Government (Florida Atlantic University / Orange Grove). Independently authored, of non-Krutz lineage.
Naming the anchor is not a claim of endorsement by its publisher, and the course is not affiliated with any of the works above. Openly licensed texts carry their licence beside them; the rest are cited, not reproduced.
