We intend to continue improving our accessibility. If you have any questions or problems, please email


Most web browsers can magnify webpages without distorting the design,  making the page more legible for visually impaired users. This feature is supported on the following web browsers:

– Microsoft Internet Explorer 7+

– Mozilla Firefox 3+

– Apple Safari 4+

The colours on our website have been chosen to provide a high degree of contrast to maximise visibility.


You can search our website for authors and titles using your keyboard. Some areas on the site now use tabbed containers to allow you to select the information you want. All the available content can be read by screen-readers when the page is loaded.


You can find additional information on our website in the form of Adobe PDF files. Clicking on a link to these files will open a new browser window. We’re working to make our most important documents fully accessible.

Alternatively you can use Adobe’s online tools to convert PDF files to HTML. For more information about reading these files with assistive technology, please visit
