Web Site Copyright Statement 

Users of this site may copy content from it without permission (excluding any material for which the Yale University Library does not hold copyright) if the Yale University Library is acknowledged in the copy and the copy is used for educational or not-for-profit purposes.

Any public domain material embedded in this site may, of course, be used without permission.

We welcome links to our sites. You are free to establish a hypertext link to any Yale University Library Web page as long as the link does not state or imply any sponsorship of your site by Yale University or any Yale University library.

Examples of permitted educational use:

  • Russell is writing a book to explain "mash ups" - a way of combining data on different web sites to make it more useful. He wants to use a copy of part of the library's web site to demonstrate a technique. He is allowed to copy a few pages to his computer and make the changes he needs to demonstrate his idea. He can show the changed page to people on the Internet and in his book. He must acknowledge the Library's web site as the original source of the pages in his academic book or on his web site (simply noting "Courtesy of the Yale University Library" and the URL is sufficient).
  • Emily is writing a paper for her school class. She will also present the paper at a conference and hopes to publish it in a journal. She would like to use several screen shots of the Library's web site to illustrate points in her paper. She is free to include pictures of the web site in her paper, the presentation and the journal article, as long as she credits "Yale University Library" as the source of the screen shots.

Open Access to Digital Representations of Public Domain Works

Yale University Library is committed to providing broad access to its collections for teaching, learning, and researching in accordance with Yale University's policy on open access to digital representations of works in the public domain.

The policy’s general principle states:  The preservation, transmission, and advancement of knowledge in the digital age are promoted by the creative use and reuse of digitized content for research, teaching, learning and creative activities.  The goal of digitization is to enhance access to the collections in Yale’s museums, archives, and libraries for student, faculty and the world.  To this end, Yale will make digital copies of unrestricted public domain collections available for use without limitations through the University’s electronic interfaces. 

Please refer to our FAQs in addition to the full policy, for additional information on privacy, restrictions, and attribution.

Exhibitions Copyright Policy

The Yale University Library, as one of the world's leading research libraries, collects, organizes, preserves, and provides access to and services for a rich and unique record of human thought and creativity. Through its web sites, the Library offers public access to a range of its collections through online exhibitions, archival finding aids, digital image repositories, and the online public access catalog.

Whenever possible, the Library provides factual information about copyright owners and related matters in catalog records, finding aids, and other texts that accompany collections or individual items. In many cases the Library may not hold copyright over items in the collections, nor images displayed online. Permission to use images and possible fees may be required by the copyright owner independently of the Library. It is the researcher's obligation to determine and satisfy copyright or other use restrictions when publishing or otherwise distributing materials found in the Library's collections. Transmission or reproduction of protected items beyond that allowed by fair use requires the permission of the copyright owners. Researchers must make their own assessments of rights in light of their intended use.

Yale University Library wants to hear from any copyright owners who are not properly identified on this or any other Yale University Library web site so that we may make the necessary corrections. Please write to with your contact information and a link to the relevant content.

Approved February, 2009.
