Bibliographic citations for articles accessed in electronic format should be given with either a URL or a URL based on a digital object identifier (DOI). If available, the DOI is preferable. Note that access dates are not required in CMS 17.

The main difference between a magazine citation and a journal citation is the volume information (for more: CMS 16 14.172). Magazines do not include volume and/or issue information even if they are available. Instead they are designated by month or season and year. If it is unclear which to use, use the Journal Citation form.
Bibliographic citations for articles accessed in electronic format should be given with a URL. Note that access dates are not required.
Page numbers are optional in the bibliography, as magazine articles are often broken up over an issue. Also, for some electronic journals, page numbers are not available. A URL should be included instead.

Citations for newspapers are optional in the reference list; however, if you are using only a few newspaper articles in your writing or if a newspaper article is particularly important to your argument, you may choose to cite it as you would a magazine. If a headline is printed in capital letters, convert it to upper and lower case.
