No author: Cite the first few words of the reference entry (usually the title) and the year. Use double quotation marks around the title of an article or chapter, and italicize the title of a periodical, book, brochure, or report. Examples: From the book Study Guide (2000) . or ("Reading," 1999).
Note: Titles of periodicals, books, brochures, or reports should be in italics and use normal title capitalization rules.
If you are citing multiple sources by multiple authors in-text, you can list all of them by the author's last name and year of publication within the same set of parentheses, separated by semicolons.
Example: (Adams, 1999; Jones & James, 2000; Miller, 1999)
