Notes: 

Cite standalone case studies as you would a book as in the first example. If the case study was published in a periodical such as Harvard Business Review, cite the case study as you would a journal or magazine article as in the second example. The title of case studies in periodicals should appear in sentence case (i.e. only capitalize the first word and any proper nouns), while the title of standalone case studies or the periodical itself should appear in title case (i.e. capitalize each word) (p. 39, "Periodicals: Basic Format," 1). IEEE recommends abbreviating periodical titles when appropriate. For a list of common abbreviations see IEEE p. 40-52. For URLs, provide the link to the publisher's website whenever possible, not the link to the library database as per APA style (see pg. 38, "On-Line Sources"). If your only option is to provide the link to the database, provide the name of the database in place of the URL (see p. 40, "U.S. Government Documents: Example," 1).
