Chicago Manual of Style - Q&A

Worried about what I mean by the serial comma* or other such terms? Begone, confusion! The Chicago Manual of Style web site has a nice reference tool in the form of a Q&A page. The page has an alphabetical index down the left side and a search tool.

*The serial comma is the comma just before the conjunction in a series. Modern American usage requires its use. Example: Planes, trains, and automobiles.
