references cited by a work can also be added. This contributes to the Crossref Cited-by service, which allows one to see what articles have cited another. Most major scholarly publishers do provide the references to each of their articles - Elsevier was a major holdout but began providing references in 2021.

Crossref does not currently support adding information about the role of each author or other contributor to an article, but this feature is planned to be released in 2025, at least for CRediT
