How does the website use cookies?

The new website uses cookies to store a variety of preferences and session information. None of it contains personally identifiable information, and all of the cookies have an expiry date, most with the current session.

The website requires cookies because each patron must have a unique session ID, and needs to be locked to a specific application server for the session. All of the other cookies are really just for convenience. For example, the website stores your preferred page length, and also stores information about the previous page you were on so we can provide a link back to that page.

There is no harm in anyone deleting all of the cookies from your computer at any time.

The chart below provides a brief explanation of each cookie.
