The setting should be ‘Medium’ for a normal text size resolution.

3.Printer-friendly version

colour etc), retain some of the essential formatting (images, headers) and send a print command to the users printer.

4.Style Sheets

In modern browsers like Firefox, style sheets for this site can be manually turned off.

This removes all formatting of pages and reads as text only, removing all background images. e.g. in Firefox go to View > Page Style > No Style.

The text size is also determined by the ‘Text size’ setting in your browser. If your setting is at a size below ‘Medium’ then the text will probably be
displayed too small to read.

For IE, you can check your Text size setting by selecting it from the ‘View’ menu option on your browser toolbar.


The main navigation is at the top of each page.

Each section of the site has main links on the left of each page and subsidiary links on the right.

There is a site-wide free text search (in the grey navigation bar towards the top right of this page).
