This document discusses strategies for participating in Crossref's Cited-By linking service, which allows members to see references from other publications that cite their own journal articles. It outlines three ways for members to deposit reference lists with their article metadata to Crossref, and three strategies for retrieving cited-by data - periodically downloading new data and updating pages; downloading data once and enabling alerts; or retrieving data on-the-fly when users view cited-by results. The document provides examples of HTTP requests members can make to Crossref to deposit references and retrieve cited-by data using these different strategies.
