Many works in our collection are protected by copyright law, so we cannot ordinarily publicly display large portions of those protected works unless we have permission from the copyright holder. Where we have the right to show page images of works, we will make every effort to do so. We are currently displaying works that are in the public domain (such as US works published before 1923), uncopyrightable works (such as works of the US government), or works where we have permission from the copyright holder. If we cannot determine the copyright or permission status of a work, we restrict access to that work until we can establish its status.
Because of differences in international copyright laws, access is also restricted for users outside the United States to works published outside the United States after and including 1876. See "What are the different Copyright statuses of items in HathiTrust, and what do they mean?"  below for more information about this restriction.
Please use the feedback form at the top of each page to let us know if our records are incorrectly restricting access to an item. For more information, see the page on HathiTrust Rights Management  and the Access and Use Policy .
Some works that are currently restricted may in fact be in the public domain. We have begun the task of investigating works published between 1923 and 1963 that were determined by initial automated methods to be in copyright. Whenever we can determine a particular work is in the public domain we will provide full access to it. In addition, if we receive permission from rights-holders to display the full-text, we will provide full access to those works. If you have information about the rights status of any of our restricted texts, please contact us using the feedback form at the top of each page.
At the current time (November 2014) we are only reviewing the copyright statuses of works that fall within the scope of the CRMS-World  project. This includes works published in United Kingdom, Canada and Australia, before:
- UK: 1943 (date range is a “rolling wall” and rolls forward each year. 2015: 1944; 2016: 1945)
- Canada: 1963 (again, date range is a “rolling wall”)
- Australia: 1955 (no rolling wall)
If you have information about the death date of an author of work that falls outside these parameters, you can still send it to us. We have reviewed these requests in the past and are re-strategizing about how to review them in the future in a more sustainable way. Any information you send will be saved for future review.
If you have information about the death date of the creator of a work (author, artist, photographer, illustrator, etc.), please send us the following information:
- Name of the creator of the work
- URL of the work in HathiTrust (e.g., http://catalog.hathitrust.org/Record/001959178 )
- Creator death date
- Source(s) of death date information with citation (we prefer two sources if available)
Below are some reliable resources for establishing death dates. We welcome suggestions for other resources. Keep in mind that the determination of a book's copyright status may extend to considerations in addition to the author's death date.

If you are a student at the University of Michigan with a disability that does not allow you to use printed books, special text versions of HathiTrust materials can be made available to you. Please see the Services for Students with Disabilities  website for more information. HathiTrust is currently working on expanding these services to students at other institutions. We cannot otherwise make exceptions for viewing online copyrighted material. Physical copies can be viewed at the library that holds the original. Physical copies may also be borrowed through interlibrary loan arrangements with your local library.
Even for works that are fully protected by copyright, you can search within the text of the item to find out how many times a particular word or phrase appears. Doing so may help you decide whether you want to seek out a physical copy, or find a specific section or phrase if the physical copy is in-hand.
HathiTrust maintains a database of every item in the Library and a corresponding rights status. Brief descriptions of the most common statuses are given below. Detailed descriptions of all statuses, with information about how they are determined and stored, are available on the HathiTrust Rights Database  page. See also our policies on Access and Use .
- Public Domain - In general, these are texts that are 1) US federal government documents 2) published in the US prior to 1923 or 3) published outside of the US before 1876. Volumes may be determined to be in the public domain for other reasons, however. See the link to the HathiTrust Rights Database page above for more information.
- Public Domain only when viewed in the United States - Works published outside the US prior to 1923 are in the public domain; however, due to the variations in copyright law in countries outside the US, it is estimated that 1876 is the earliest date foreign works may still be under copyright. Therefore, users accessing the volume from US IP addresses will have access to the works published outside the US between 1876 and 1923; however, users with non-US IP addresses will not.
- In-copyright - Texts that do not meet the criteria for Public Domain (e.g,. US post-1923 and not a government document) are treated as in-copyright.
- Available to nobody; blocked for all users - Works with this status may have been deleted or access may be blocked e.g., pending a rights investigation. This is typically a temporary status while an issue is resolved.
- Available to everyone in the world - In-copyright Works that the University of Michigan has been given permission by the copyright holder to display on a broad basis. The scope of permission granted may restrict some use, such as not allowing the sale of reprints. Please send inquiries about individual volumes to email@example.com .
- Undetermined copyright status - Instances where copyright status could not be determined by automatic processes from bibliographic data, copyright research is only partially complete, or an ambiguous, unclear, or otherwise time-consuming situation was encountered. Items with this status are treated as though they are in copyright.
Please use the feedback link at the top of each page, and we will address your questions. Any issues concerning copyright permissions for items will be addressed within a business day of notification. For more information, see the HathiTrust Take-Down Policy .
For Rights Holders
Yes. You can grant permission using our Permissions Agreement. The Permissions Agreement provides a range of Creative Commons license options for you to choose from. Creative Commons  is a non-profit organization that has created legally enforceable licenses that allow rights holders to grant specific uses of their creative work, like your book. The licenses provide a range of choices - from placing your work in the public domain, meaning you are giving up the copyright in the work, to allowing others to copy and use your work with attribution to you. The licenses are flexible and give you control over your work. We would be glad to answer any questions you have about the licenses or permissions process. Please contact firstname.lastname@example.org  for assistance.
The University of Michigan is the legal home of the HathiTrust partnership. Thus, the permission is granted formally to the University of Michigan.
HathiTrust is a digital preservation repository that was created by research libraries,and is participated in by more than 100 libraries internationally, to ensure the long-term preservation of their combined collections. Member libraries and other collaborating entities digitize titles from their collections and deposit them HathiTrust for long-term preservation and lawful access services.
HathiTrust only makes uses of preserved materials that it is entitled to make under U.S. copyright law. No viewing access to copyrighted publications is provided without explicit permission of the copyright holder. An example of the way in-copyright works are represented in HathiTrust is available at http://hdl.handle.net/2027/mdp.39015066724454 .
Yes. There are two ways to do this:
1. Via HathiTrust
Rights holders can make their works publicly available in HathiTrust using our permissions agreement . The agreement includes options that allow rights holders to assign Creative Commons licenses to their works or allow their works to be printed on demand if desired.
If a work in question was digitized by Google, full PDF download will only be publicly available if a Creative Commons license is assigned. You can determine if a work was digitized by Google by searching for it on Google Books. We can also assist in determining if a work was digitized by Google. If a Creative Commons license is not selected in the permission form for a Google-digitized work, the work will be readable online by anyone, but only members of HathiTrust partner institutions will have the ability to download a full PDF (see http://www.hathitrust.org/help_digital_library#FullPDF  for further details). Please feel free to contact us at email@example.com  with any questions.2. Via Google
Rights holders can also open works that were digitized by Google on Google Books if desired, by following the directions below:
- Sign up at for the Google Books Partner Program  (click "Get Started Now"). This process will take a few minutes and will give you a special Partner Program account and interface from which you can manage how your books are shown on Google Books.
- When you are ready, you can use Google's support form to add library-scanned books  to your account and make them available online.
US State Government Documents
It depends on whether you are talking about work by employees of the federal government of the United States OR work produced by employees of an individual state. Under US Copyright law, works produced by federal employees working in the scope of their employment are not eligible for copyright protection – such works are in the public domain (see http://www.usa.gov/copyright.shtml ). However, state government documents are not covered by this rule, as state governments may chose to protect their copyrights as they wish – they are presumed to be subject to copyright by the state for which they are produced. As a result, there is a patchwork of protections covering state government documents.
It is not always clear from examining a given state government document whether it is protected by copyright. Some documents may have a copyright notice or a Creative Commons license on them. In the absence of some kind of notice on the document, you may need to contact the department responsible for the work.
If you have a particular document you want to see made available, please cite to the relevant departmental or state policy governing copyright in that document and send that information to HathiTrust (use the feedback link at the top right of every page). Currently, we are beginning to systemically investigate the status of state government documents in the HathiTrust and are in the early stages of a project to make determinations about the copyright status of state government documents.
If you are a state employee with the capacity to grant permission to HathiTrust to make some or all of your department’s documents available, you can identify the documents and give us permission with the HathiTrust permissions form (see http://www.hathitrust.org/permissions_agreement ). If you are unsure whether you have the authority to make such a declaration, feel free to contact us (via the feedback link or at firstname.lastname@example.org ) and we will help you through the process.
Golan v. Holder FAQ
Originally filed in 2001, Golan v. Holder, originally named Golan v. Ashcroft, was a suit challenging the constitutionality of elements of the Uruguay Round Agreements Act (URAA), a bill passed in 1994 in order to implement elements of the Uruguay Round of the General Agreement on Tarriffs and Trade (GATT). The section of the URAA at issue restored copyrights to foreign works published without compliance with US formalities, such as a copyright notice or registration or renewal.
The constitutional question at issue in Golan was whether restoring copyright rights to works already in the public domain was a violation of the First Amendment right to free expression, and whether the “limited times” clause of Article I Section 8 of the Constitution disallowed the restoration of lapsed or otherwise expired copyrights.
In a 7-2 decision, a majority of the Supreme Court ruled against Golan, stating that Congress was well within its power to pass the URAA and restore copyrights. Writing for the majority, Justice Ginsburg stated that URAA did not violate the First Amendment or Article I Section 8, as “(n)either the Copyright and Patent Clause nor the First Amendment, we hold, makes the public domain, in any and all cases, a territory that works may never exit.”
The Supreme Court’s ruling in Golan v. Holder has no effect on the operations of HathiTrust, or rights identification projects such as the Copyright Review Management System (CRMS) that HathiTrust partners have undertaken. Since we had been following the existing law that the plaintiffs in Golan had sought to overturn, the Courts failure to do so does not affect us in any material way at this time. Had the Court decided to overturn the Uruguay Round Agreements Act (URAA) on the other hand, the number of non-U.S. works in HathiTrust that were in the public domain would have been expanded. As it is now, our situation remains the same as it was before the ruling.
Yes. While the case has no immediate impact on HathiTrust, it has significantly upset some of the basic assumptions about copyright law under which libraries have been operating. Before Golan, it was generally accepted that once a work had entered the public domain, it would remain there. While URAA did restore copyright to a class of public domain works, it was a sufficiently special case to be treated as an exception to the general principle as opposed to precedent. After Golan, it would be possible, if unlikely, for Congress to restate copyright protection to works previously understood to be in the public domain. As public domain works make up a large portion of the works in HathiTrust, this could limit the scope of the access we currently provide.
