Library: OER: Copyright

Public domain

PUBLIC DOMAIN: Works which are not owned by someone, and therefore not protected by copyright.

A work may be in the public domain because:

Created before copyright laws (example: The Iliad, Canterbury Tales),
its copyright protection has expired (example: Adventures of Huckleberry Finn, Moby-Dick; or, The Whale),
it never had copyright protection or its protection was lost (example: a work published before March 1, 1989 and did not carry a copyright notice),
it was dedicated to the public domain.

In addition, the following items are never covered by copyright:

works created by the U.S. government (except under contract).
reprints of works in the public domain (but a license may restrict use.)
ideas, facts, and common property (i.e., calendars and phone books)
federal laws and court decisions
words, names, slogans and phrases
most blank forms
recipes, discoveries, procedures, and systems (but not the words that describe them.)

Initial US copyright	Current copyright status
before 1927	Public domain
1927-1963	Still protected by copyright law if the copyright was renewed; check for renewal at Stanford Copyright Renewal Database and the Library of Congress Copyright Database to cover the entire date range.
1964-1977	Still protected by copyright law. Protected 28+67=95 years from initial copyright date.
1978-	Still protected by copyright law; however, these rules are very complex. Generally speaking copyright protection ends 70 years after death of author.

Just because an item is old doesn't guarantee that it is part of the public domain. If you're at all uncertain, get permission from the creator or owner to use or copy the work.

Creative commons

Creative commons licensing is at the heart of OER. Creative Commons licenses enable the sharing of knowledge and creativity. Over 2 billion works are in the Commons.

You can license your own work using a CC license, and displaying it on your page. There are 6 creative commons license options, plus CC0 (CC zero), which dedicates the work to the public domain.

For help choosing a license, follow the steps of the CC chooser.

Attribution

Although OER are free to be used, one of the key tenets of that usage is attribution. Depending on the specifics of a resource’s licensing terms, you will at least need to acknowledge the work’s creator.

A lack of specific attribution instructions does not mean that a work should not be attributed. Rather, you must put together an attribution statement to the best of your ability. This statement should include:

Any copyright notices posted by the copyright holder
Some form of identification of the author (a screen name is acceptable if you cannot locate an author name)
The name of the resource
The license, and if possible, a link to the license terms
If you have made any changes to the resource, a statement that this is a derivative work
