A cookie is a small amount of data that is sent to your browser from a web server and stored on your computer's hard drive. The HTTP standard permits servers to deploy cookies to web browsers, which record settings or preferences for a fixed period of time. Unless the viewer has set his/her browser not to accept cookies, this allows some websites to track visitors.
As we say in our privacy page, our policies prevent our collections from using cookies for any purpose but to allow visitors to set interface preferences, such as how items should be ordered in lists. Usage of a cookie is in no way linked to any personally identifiable information while on our site. Once the user closes his or her browser, the cookie simply terminates. For instance, setting a cookie allows an EServer member to avoid having to log in with a password more than once, thereby saving time while on our site. If a member's browser rejects the cookie, he or she may still use our site.
