Because of space limitations, references may be abbreviated. Consider the following examples for a poster with numerical citations ... 

The third ACS-approved approach to citing the literature is to use authors last names and year of publication (author name, year). This format is relatively uncommon in ACS journals but is frequently used in journals of other scientihc disciplines, such as Ecology and Reviews of Modern Physics. With the author—date citation technique, the authors last names, followed by a comma, a space, and the year of publication are placed in parentheses (or brackets in some journals). Publications with three or more authors are referred to by the last name of the first author, followed by et ah, a comma, and the year.
