Internet, Web, and Other Post-Watergate Concerns
Q. When publishing a web address in a print publication, do you recommend underlining it (as it would appear on the web), bolding it, or doing nothing? Is one way better than another when the web address is at the end of the sentence (thus, followed by a period)? Example: For more information, visit www.chicagomanualofstyle.org.
A. No, we don’t recommend any special treatment for URLs, and we don’t worry when they come at the end of a sentence. (Sometimes, your browser won’t fuss if you include a period at the end of a URL in the address box—try it.) You can find samples of Chicago-style citations that include URLs right here at this site.
