When citing electronic material, in addition to the basic information included as with print references, you must also, in general, include the URL (link) to the item as well as the date you accessed it. Two tips to keep in mind: provide the most direct url possible and if a DOI is listed instead of a URL, it is not necessary to include the date accessed. DOI is preferred over URL.
Please note: Some browsers may show italicized text as underlined. When preparing bibliographies based on any of the formats addressed by this series, italics are specified, and should be used. If you don't see an example for your type of reference, consult the manual itself.
