Footnote system fully integrated

Published on June 23, 2025

Last updated on June 6, 2026

The long-planned automated footnote engine is now live and working inside chapters. This system supports inline references with automatic numbering and back‑links, dynamic retrieval of CPT data (books, concepts, etc.), and CPT‑specific icons with smart linking based on type.

CPT types now supported in footnotes: Artist Profiles, Book Citations, Lexicon Entries, Biographical Figures, Movies Referenced, and Quote Library (coming soon).

Footnotes now pull directly from related CPTs, showing titles, definitions, cover images, and even source links when available — all while maintaining reversible reference arrows (↩︎) for context tracking.

Manual references supported

Not all references are CPTs. A fallback system allows standalone notes to be inserted manually, using shortcode attributes like text="...". These render in sequence with all other footnotes and maintain numbering integrity.

Songs referenced: structured support added

A new ACF field is now being added to each chapter to store secondary songs referenced (excluding the main one). These appear as a styled list at the bottom of the footnotes section, bolding the artist name and keeping formatting consistent:

Songs Referenced:
Tom Petty – Learning to Fly
Peter Gabriel – In Your Eyes

This ensures a clean visual trail of sonic context for every chapter — especially important for readers tracing intertextual music references.

Toward auto-updating artist/song indexes

The existing manually built artist–song–chapter spreadsheets are now being considered for automation. With all primary artists already stored as CPTs (and more referenced ones being added), future updates will explore dynamic artist/chapter cross-lists, alphabetical and chronological views, and public song indexes updated automatically via ACF fields.

Chapter data normalization continues

As part of the footnote integration, each chapter is now being reviewed and structured around:

  • Featured artist(s) → tied to CPTs.
  • Referenced books, profiles, concepts, movies → footnoted and linked.
  • Inline quote blocks → migrating to reusable ACF/HTML fields.
  • All external sources, even Wikipedia quotes → structured as manual references.

This marks a significant shift from static references to semantic, linkable content blocks.

Status overview

✅ Completed:

  • Footnote engine fully deployed with CPT integration.
  • CPT-specific icons and dynamic linking based on post type.
  • Manual notes and non-CPT references supported.
  • Songs Referenced field added to chapters.

🔧 In progress:

  • Automate artist/song chapter spreadsheet via CPTs.
  • Create Quote CPT to expand footnote coverage (💬).
  • Continue migrating embedded content to structured fields.

This footnotes system ties together every element introduced so far — turning chapters into relational nodes that link books, profiles, concepts, songs, and quotes in a transparent, reusable way.
