Suppl

Suppl is an abbreviation for supplement, used in publishing and bibliographic records to indicate material that accompanies a publication but is not part of its main content. The term derives from the Latin supplementum and appears in styles such as Suppl. or Supp.

In scholarly journals, a supplement may be a separate issue or a collection appended to a volume. It is often designated with Suppl. or Supp. and may have independent pagination, frequently using a prefix such as S for page numbers (for example, Journal X 12(3 Suppl): S1–S50).

Contents can include extended methods, additional data, tables, figures, or review articles. Online publishers frequently provide Supplementary Information or an Online Supplement linked to a specific article; access may depend on subscription or purchase.

Suppl vs supplementary material: A supplement issue is a discrete component of a journal, while supplementary material is content tied to a particular article. The editorial and peer-review status of supplements varies by journal.

In library catalogs and citation styles, Suppl. is one of several abbreviations used to denote ancillary material; common alternatives include Supp. and Supplement. The concept helps readers locate extra context without changing the main publication's narrative.
