About CDL Services and library materials information

CDL operates a variety of Sites and Services that amplify the impact, scholarship, and resources of the University of California. One of these Services is UC Library Search, which is the primary discovery service for the collections of the UC Libraries. UC Library Search users can find, request and manage materials through their UC Library Search account. Each campus chooses how to manage information associated with user accounts for the users affiliated with their campus. A limited amount of this information is shared with CDL. If you have questions about the use or retention of your information in UC Library Search, contact your campus library or consult the library’s privacy statement.

When users find materials through UC Library Search that are not available directly from their campus library, they can make a request to have those materials sent from another library. If you use this functionality, CDL collects the information about your request in order to facilitate the request’s completion. Information about these requests is anonymized 30 days after each request transaction has been completed (for example, after a book you borrow has been returned).

Personal Information we collect

Some of the information we collect can directly or indirectly identify you. This is called your “Personal Information”. We only collect Personal Information from you that is relevant and necessary for us to provide services to the public or required to meet our obligations under law.

Additional notice for the European Economic Area (“EEA”), United Kingdom (“UK”), and Switzerland.

Controller: The Regents of the University of California, a corporation established under the laws of the Constitution of the State of California, and duly incorporated and organized under the laws of United States of America, having its registered address at 1111 Franklin Street, Oakland, CA 94607, is the “controller” responsible for the processing of personal data in connection with CDL Services. This means that we determine and are responsible for how your personal data is used.

UC is the controller of the Personal Information we hold about you in connection with your use of our Services. Depending upon your relationship with UC, UC may use your Personal Information where necessary to perform its obligations under a contract with you, or where necessary to fulfill a request you have made to use or participate in a CDL Service; where required by law, and/or where necessary for the legitimate interests of UC, provided that there is no overriding impact on your interests or rights. In some cases, we may ask you to grant us separate consent to use your Personal Information.

Marketing and Advertising

From time to time, we may contact you with information about our services, including sending you marketing messages and asking for your feedback on our services. Most marketing messages we send will be by email. For some marketing messages, we may use Personal Information we collect about you to help us determine the most relevant marketing information to share with you.

We will only send you such marketing messages if you have given us your consent to do so. You can withdraw your consent at any time by clicking on the unsubscribe link at the bottom of our marketing emails.

In the event of such a transfer, we ensure that: (i) the personal data is transferred to countries recognized as offering an equivalent level of protection; or (ii) the transfer is made pursuant to appropriate safeguards that require the recipient to treat the personal data in a manner that is essentially equivalent to that guaranteed in the country you are in. If you are located in the EEA, United Kingdom or Switzerland, these safeguards include entering into agreements that incorporate the standard contractual clauses adopted by the European Commission and approved by the UK Information Commissioner.

If you wish to inquire further about the safeguards used, please contact us using the details set out in this Privacy Statement.

Where permitted by law, non-personally identifiable information and Personal Information may be automatically collected through the standard operation of CDL services or through the use of “cookies” or “internet tags” and other similar techniques. If you want more information on how to restrict cookies see below.

We and our third-party partners and providers may use cookies to automatically collect certain types of usage information when you visit or interact with our email communications and Services. For example, we may collect log data about your device and its software, such as your IP address, operating system, browser type, date/time of your visit, and other similar information. Our emails may also contain tracking pixels that identify if and when you have opened an email that we have sent you, how many times you have read it and whether you have clicked on any links in that email. We may also collect analytics data or use third-party analytics tools to help us measure usage and activity trends for our online services and better understand the individuals using our services. We also may collect location data, including general geographic location based on IP address.

CDL may use three types of cookies:

  • Essential Cookies. These are placed on your computer to let our Site function as intended, by allowing the pages to display correctly. Without these, our Site would be prevented from working and would be unusable.
  • Preferences & Functionality Cookies: These cookies allow our Site to remember how it behaves or looks based on your preferences (e.g., your preferred language or the region you are in). These cookies can also assist you in changing text size, font, and allow you to personalize the pages based on your preferences. These cookies help enhance your experience and disabling these cookies may make our Site less functional; disabling these cookies, however, should not prevent our Site from working.
  • Third-Party Analytics Cookies: We use third-party cookies for analytics. The use of analytics cookies allows us to improve the Site and enhance user experience. The analytics cookies set on your browser allow us to recognize and count the number of users to the website, see when users are using the Site, and see how users interact with the Site and its different functions. Analytics cookies show us which of the Site pages are most frequently viewed and help us record any difficulties you have with the Site.

We work with third-party partners to provide analytics services. For example, we use Matomo to recognize you and link the devices you use when you visit our Services on your browser or mobile device, log in to your account on our Services, or otherwise engage with us. We share a unique identifier, like a user ID, with Matomo to facilitate the service. Matomo allows us to better understand how our users interact with our Services and to tailor our content to you. For information on how Matomo collects and processes data, as well as how you can control information sent to Matomo, review Matomo’s website, “Personal data Matomo analytics collects and why” located at

Interim version of the above changes, to be used until we finish removing Google Analytics (in process):

We work with third-party partners to provide analytics services. For example, some of our sites use Matomo or Google Analytics (“Analytics Providers”) to recognize you and link the devices you use when you visit our Services on your browser or mobile device, log in to your account on our Services, or otherwise engage with us. We share a unique identifier, like a user ID, with Analytics Providers to facilitate the service. These Analytics Providers allow us to better understand how our users interact with our Services and to tailor our advertisements and content to you. For information on how Analytics Providers collect and process data, as well as how you can control information sent to Analytics Providers, review Matomo’s website Personal data Matomo analytics collects and why” located at or Google’s website, “How Google uses data when you use our partners’ sites or apps.”

You may also set your email options to prevent the automatic downloading of images that may contain technologies that would allow us to know whether you have accessed our email and performed certain functions with it. Alternatively, you may wish to visit, which contains comprehensive information on how to do this on a wide variety of desktop browsers.
