Most style guides will ask you to include your source’s publication date in your citation. However, there are other temporal questions which add further nuance to your citation which you should be aware of.
- Has your source been published more than once, as separate editions? Also, did it appear in a particular edition of a larger work?
- If your answer is yes to either of these questions, you may need to provide further information in your citation regarding the precise edition that you are citing, and when that edition was published.
- Did you access your source on a particular date?
- If you are using an online source, you may need to include in your citation the exact date on which you accessed it, as online sources are frequently updated.
