Headers and footers
These are very useful in larger documents, and enable any photocopied pages to be easily identified.
It is good practice to put the document title and publication date on all documents. This information could appear at the top or the bottom of the page.
If a document is longer than two pages, each page should be numbered.
How the headers and footers are aligned, and how they show their information, is up to you. For example, you could use a spaced dash on either side of a page number, eg - 2 -.
Make sure the style you use fits in with your departmental house style. Be consistent within each document.
Headers and footers should always be at least one line of space away from the main body of text, to avoid being mixed up with it. They are often in a smaller point size or different font so that they are clearly subsidiary to the main text.
