How to quote resources that are no longer published?

Citing discontinued resources is feasible through verifiable archival versions or library access. Key principles include prioritizing permanent archival links (e.g., DOI, permalinks), clearly identifying the archived source location, and adhering to specific style guides. If the original is entirely inaccessible, transparently note "accessed via archive" and provide retrieval dates. Verify source authenticity through reputable digital repositories or institutional holdings. When citing discontinued print publications, consult major library archives or copyright holders for permissions; for unpublished materials, secure explicit rights. Digital persistence remains paramount - services like DOI, JSTOR, Portico, Wayback Machine, or publisher archives offer vital preservation. Prioritize persistent identifiers and confirm stable archival policies to ensure future retrievability. Implement citation by identifying verified archives housing the material, then format the citation per your discipline's style manual (APA, MLA, Chicago). Standard practice combines the original publication details with archival information, such as: Author. (Year). *Title*. Archive Name. URL/Permanent Link (Accessed YYYY-MM-DD). This practice maintains scholarly integrity, enhances source verification, and allows readers to trace the provenance of inaccessible works.
