When citing outdated information or resources, how should it be indicated?

When citing outdated information or resources, it should be explicitly indicated to maintain scholarly transparency and integrity. Failure to do so risks misleading readers about the current state of knowledge. The key principle is to transparently note the obsolescence while still providing the citation for reference. When the outdated source remains relevant for historical context, foundational understanding, or tracking intellectual development, cite it alongside more current scholarship. Crucially, directly alert the reader to its outdated status. The applicability includes referencing seminal historical works where the original publication date is understood to indicate older information. To implement this, add an explicit annotation within the citation. Option 1: Place a brief notice, enclosed in square brackets immediately after the citation, such as [cited for historical context] or [superseded by newer evidence]. Option 2: Include a concise explanatory sentence in the main text preceding or following the citation, stating its purpose despite being outdated. This practice preserves academic honesty, clarifies source relevance, and prevents misinterpretation.
