- month: Month of publication (ignored if the date field is used).

If the city is not well-known, you may add a county, region, or state. States in the U.S. are denoted by a two-letter code; for example:

- nopp: if set to any value,
page=/pages= do not generate 'p.' or 'pp.'. E.g.
at= has the same effect.
- at: Position within the resource when page/pages is inappropriate or insufficient. This parameter is ignored if page/pages is specified. Examples of usage of at: at|para. 14 (when citing a source without page numbers), at|02:56 (a film or audio timestamp), at|no. 456 (something in a numbered list), at|p. 6, col. 2 (for a page and a column because "column" is not a Citation template parameter), or at|sec. F pp. 4–6 (for a section and a page within the section, "section" not being a parameter).

- doi_inactivedate: Date on which the DOI was observed to be not functioning.

- bibcode: The document's bibcode in the Astrophysics Data System, e.g., 1924MNRAS..84..308E
- url: An url of an online location where the book can be found.

- An abstract or information page, if no DOI or PMID record is available
- accessdate: Date when the url was accessed.
- format: format of online documentation if not html (e.g. pdf).
- archive parameters (if used, both must be used together)
- archiveurl: The URL of an Web archiving|archived copy of a web page, if (or in case) the url becomes unavailable. Typically used to refer to services like WebCite and Internet Archive|Archive.org.
- archivedate: Date when the item was archived. Should not be wikilinked.

Punctuation specified by this parameter will appear within the cite span, and consequently before any icons added by metadata-using software (e.g. library browser plugins). Hence this parameter should be used instead of manually appending data to the citation. This parameter is ignored if quote is specified, when postscript|. is forced.
- ref: An explicit ID for Harvard references; see #Anchors for Harvard referencing templates|Anchors for Harvard references
