What are cookies

We are continually trying to develop and improve our website, and, in order to do this, we sometimes place small amounts of data on your computer. This data is called a ‘cookie’ and is standard practice on most organisations' websites. 

Cookies are used for many reasons, for example: 

  • To allow us to know when you have logged in to certain areas of our website (e.g. the Library catalogue) 

  • To remember your language selection so that you see your language choice the next time you visit 

  • When you fill in questionnaires, to allow you to move back through your choices without losing your selections 

  • To learn how our website is used, in order for us to continually improve through statistical data 

Cookies are used across most of our websites, but we do not use these to try and identify our users. You can manage or delete cookies as you wish. For further information visit
