A finished article or report should have a limited number of simple, informative headers and footers — perhaps a title or section head and a page number. Work in progress requires additional information; e.g., the author's name or initials, the date, and a statement that this is a draft. To help with this, I have made Lance Berc's1 three part headers and footers the default page style. The commands
\lhead{<item>}
\chead{<item>}
\rhead{<item>}
sets the left, center, and right parts of the headers. The
corresponding commands for footers are\lfoot{<item>}
\cfoot{<item>}
\rfoot{<item>}
In the twoside document style, the macros switch the right and
left items on even numbered pages. The \pagestyle command
overrides the three part option.
