Helpful Hints
If no revision date available include an access date.
Use a DOI instead of a URL if it is available.
See 14.18 for where to put line breaks for DOIs or URLs.
Works that have substantial authored entries may most appropriately be cited by individual entries. These would also be included in the bibliography.
Any edition other than the first must be specified.
Include _ ed. _ vols. after title if needed.
In a work that is arranged alphabetically by entry include s.v. or s.vv. (plural) followed by the names of the entry/entries instead of the page number.
