Notes: 

The title of the report should appear in sentence case (i.e. only capitalize the first word and any proper nouns) (see p. 39, "Reports and Handbooks: Basic Online Format," 1). Do not cite a specific section of a report, cite the report as a whole. Abbreviate the name of the government entity when possible; use commonly known abbreviations or consult the list in IEEE p. 40-52 (see p. 39, "Reports and Handbooks: Basic Online Format," 1). Consider including an access date for online materials, especially if you do not know the date of publication; when the access date is used in place of the date of publication, place it immediately after the URL (see p. 39, "Reports and Handbooks: Examples," 2).
