OCLC Cookie Policy


In line with changes in European legislation, OCLC has published a definitive list of its websites and services which use cookies - small text files containing data which are downloaded to your computer when you visit one of our websites or use certain OCLC services. The vast majority of websites use cookies and tracking technologies. Cookies are useful because they help OCLC arrange the content and layout of our websites and recognize those computers that have been to our websites before.

They allow us to remember users’ preference settings and play an important role in helping OCLC enhance the usability and performance of our websites and services, as well as your experience using them. Some cookies are also essential to enable you to move around our website and use its features. They help us to identify which of our articles are the most popular and the types of journey visitors have to our websites.

Below is a short description of generally recognized categories of cookies, though you should note that OCLC does NOT use all four (4) of the categories.

1. Essential Cookies

Description: These cookies are essential for the running of our websites. Without the use of these cookies parts of our websites or services would not function.

OCLC’s Use of Essential Cookies is documented in the OCLC Cookie List.

2. Analytical Performance Cookies

Description: These types of cookies are used to monitor a website’s performance and how users may use it. These cookies provide information that helps the site owner provide better products to their users and also to identify any areas that may need maintenance.

OCLC’s Use of Performance Cookies is documented in the OCLC Cookie List.

3. Functional Cookies

Description: Functional cookies are used to remember your preferences on our websites. This can be anything from remembering your city in a weather forecast or saving your username.

OCLC’s Use of Functional cookies is documented in the OCLC Cookie List.

4. Behavioural Advertising Cookies

Description: Use of cookies for online behavioural advertising is a way of providing advertisements on the websites you visit and making them more relevant to your interests. This is done by grouping together shared interests based upon previous web browsing activity. Advertising is then displayed to you when you visit a website which matches these interests. Behavioural advertising is based upon your web browsing activity over a period of time - so it's different to advertising you may see when you're looking for something online using a search engine (e.g. Google) or on the website you may be visiting at a particular time.

OCLC does NOT use Behavioural Advertising Cookies

We may also track IP addresses. An IP Address is a number that can identify an Internet Service Provider and country location. It cannot provide other personal information.

OCLC maintains a list of the cookies we use on our main sites and services, which may be found here.  The list also contains a short description of the cookie and the period of time the cookie will remain on your device if you take no actions to block or remove the cookie.  OCLC operates dozens of Web sites and services and we will continually work to keep this document up to date with accurate information.
