What is copyright?
A form of protection provided by the laws of the United States for "original works of authorship", including literary, dramatic, musical, architectural, cartographic, choreographic, pantomimic, pictorial, graphic, sculptural, and audiovisual creations. "Copyright" literally means the right to copy but has come to mean that body of exclusive rights granted by law to copyright owners for protection of their work. Copyright protection does not extend to any idea, procedure, process, system, title, principle, or discovery. Similarly, names, titles, short phrases, slogans, familiar symbols, mere variations of typographic ornamentation, lettering, coloring, and listings of contents or ingredients are not subject to copyright.
Three requirements for copyright:
Most works are protected by copyright
Almost all creative and intellectual work is protected by copyright. Remember that facts are not subject to copyright.
Copyright is automatic
Works do not have to have copyright notice posted or be registered in any way in order to be protected by copyright. This means that everything from a novel to a napkin doodle has full and automatic copyright protections.
Copyright lasts a long time...
Works are protected for the life of the author, plus seventy years. If a work was “made for hire [pdf]” it is protected for 95 years from publication or 120 years from the creation of the work (whichever is less). The rules are different for works made before 1978 and incredibly complicated. Try this copyright slider from the Copyright Advisory Network when in doubt.
...but not forever
Works with expired copyright pass into the public domain and are available to be used in whatever way you’d like. Also not protected by copyright are works created by the US government (and some states), facts, ideas, and methods.
The rights of copyright
Copyright is seen as a bundle of rights. These rights include the right to:
Because these rights are imagined as a bundle, the owner of the copyright can give away, sell, or otherwise license some or all of these rights to others (as when an author negotiates a contract - they may give the publisher the right to copy and distribute the work but not make future derivative works, for instance).
What Copyright Protects
Copyright only applies to the following kinds of works:
This list encompasses most kinds of creative or intellectual expression. Works must also be "fixed in a tangible medium of expression". Unfixed works like improvised music, speeches, or dances are not protected by copyright.
Remember: copyright is not designed to reward hard work but, rather, to foster creativity. Works that took a lot of effort to put together but that don't contain original expression do not qualify for copyright protection.

How long does copyright last?
Copyright protection does not last forever. The United States has had several copyright codes in its history, so depending on when a work was created, it may or may not be protected by copyright. The American Library Association created the Digital Copyright Slider to help determine whether the material needed is held under copyright or if it is in the public domain
For new works created in the United States, protection begins with creation of the work and lasts 70 years after the date of creation. At that time, the work passes into the public domain. For older works created in the United States, cessation of copyright protection and passage into the public domain depends on a variety of factors. The chart below provides some basic guidelines for determining the copyright status of works created in the United States.
Date of Publication |
Conditions |
Copyright Term |
Before 1924 |
None |
None. Work is in public domain due to copyright expiration. |
1924-1963 |
Published with a copyright notice |
28 year + possibility of renewal for 67 years. If not renewed, it is in the public domain. |
1964-1977 |
Published with a copyright notice |
28 years for 1st term + automatic renewal for 67 years. |
1924-1977 |
Published without a copyright notice |
None. In the public domain due to failure to comply with required formalities. |
Before 1978 but never published or published between then and 2002. |
January 1, 1978, which is the effective date of the current Copyright Act |
Lifetime of author + 70 years, or December 31, 2002, whichever is greater |
1978 or later |
Moment the work is fixed in a tangible medium of expression |
Lifetime of author + 70 years. If work is of corporate authorship, the shorter of 95 years from publication, or 120 years from creation |
What happens when copyright expires?
When the term of copyright expires, a work is said to enter into the public domain.
The public domain refers to works that are not copyright protected and can be used freely, without seeking permission. Works can pass into the public domain through various ways, so it is important to always check carefully to determine if a particular work is really in the public domain before assuming you may use it without permission.
Works that exist in the public domain, include:
Anyone may reproduce, redistribute, or adapt works in the public domain. Permission for use is no longer required.
Due to the Copyright Term Extension Act of 1998 (also known as the Sonny Bono Act), no copyrighted works will enter the public domain until 2019.

What does the right of "first sale" mean?
The "first sale" doctrine says that a person who buys a legally produced copyrighted work may "sell or otherwise dispose" of the work as he or she sees fit, subject to some important exceptions (Section 109a). "First sale" gives you the right to loan a legally purchased book or CD to your friend. Historically libraries have heavily relied on the first sale doctrine to lend books and other items to their patrons.
The first sale clause was enacted during a time when most copyrighted works were produced in physical formats that made such works difficult to reproduce on a large scale. Many protected works including books are now produced digitally, however, copyright owners have lobbied Congress for new laws that some feel may undermine the "first sale" doctrine.
Additionally, many publishers (most notably music publishers) are now creating works to include technologies that interfere with the "first sale" doctrine. Software companies also attempt to circumvent the first sale doctrine by characterizing the consumer purchase as a license rather than a sale.
First sale issues are entangled with licensing and Digital Millennium Copyright Act issues. To learn more about The Digital Millennium Copyright Act please see the American Library Association's Introduction to the DMCA.
