Tilleggskapittel

Tilleggskapittel is a Norwegian term for a supplementary chapter added to a book, report, or other extended document. It denotes content that supports the main argument or narrative without being essential to it. The tilleggskapittel is typically placed in the back matter after the main chapters and may be labeled as an appendix, an addendum, or as its own numbered chapter.

The purpose is to provide material that would interrupt the flow if included in the main text. Common contents include detailed data tables, experimental procedures, mathematical derivations, program code, transcripts, maps, translations, or methodological notes. It may also contain updates or revisions for later editions.

In use, a tilleggskapittel is referenced from the main text, allowing readers to consult it for verification or deeper understanding without requiring all readers to engage with the supplementary material. The exact placement and labeling depend on the publication's style guide, and terms may vary by publisher; some works may simply use the term appendix (vedlegg) or similar.

Etymology: tillegg means addition, kapittel means chapter. The term is primarily found in Norwegian-language publishing and is used in Bokmål and Nynorsk contexts.
