U.S. copyright law (Title 17 of U.S. Code) defines what owners of copyrighted works can do with respect to copying, distributing, performing, or creating derivitive works. The owners can determine what others can do with their work by transferring ownership or granting licenses for specific activities.
What is protected under copyright law?
Original works protected by copyright law must be "fixed in a tangible medium of expression" and may consist of the following categories:
To be "fixed in a tangible medium of expression" means that the work can be saved in some form, such as a computer file, sound recording, or even a napkin.
Works must also contain some originality, rather than being a collection of factual information where no original content is provided.
Any original work created in the United States receives automatic copyright protection without the need to register your work with the U.S. Copyright Office. However, many copyright owners choose to register their works so they can receive the full benefits of the law.
Copyrighted works may or may not display a copyright symbol (©). You do not need a copyright symbol to have your work protected by copyright law.
What is not protected by copyright?
When do I need to consider copyright law?
In education, copyright issues arise anytime you...
Fortunately, Section 107 of the Copyright Law provides allowances for the fair use of copyrighted materials "for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research." See the Fair Use tab for more information about Fair Use.
What does it mean to be in the public domain?
Works in the public domain are considered "public property" and can be used by anyone, without the need to seek permission. They may consist of works whose copyright have expired, works placed in the public domain by their creators, and works ineligible for copyright protection. Works created as part of government work are also in the public domain.
What other models exist for sharing copyrighted work?
Modern approaches to copyright take the form of alternative licensing practices and access models that provide content creators with more options for sharing their work. These consist of Creative Commons licenses and Open Access journals. In both cases, original authors maintain the copyright to their works, but are only choosing to make their work more accessible.
Creative Commons licenses have a basic approach that allows content owners to share their work openly, with pre-defined limitations on how they are attributed, how their work can be used, and by what types of institutions. Works with a Creative Commons license are usually clearly labeled with the specific license, which will indicate any attribution and use limitations.
Open Access journals are an alternative to traditional scholarly publishing mechanisms where copyright is typically held by the publisher, who determines licensing for use of individual journal articles. Open access journals are published on the open web and accessible to all for downloading, linking, and sharing. Another form of open access publishing is posting your work to your own website for sharing.
