Copyrights are a good business investment. According to CopyrightKids.com, they protect the creators and owners of elements key to a company's brand -- including books and publications, music, films and even paintings -- from being copied, performed or displayed without permission. If you have an item or piece of intellectual property that you want to reproduce, first find out who, if anyone, owns its copyright. This is not always possible due to natural copyright. However, most published works or business items are registered with the U.S. Copyright office.
Look for a copyright symbol to identify the author or owner of the copyrighted item or work. For example, in books, this person or business name is often found next to a copyright symbol (a "C" inside of a circle) after the title page. You can also contact the owner directly, if possible, to ask if he still holds the copyright to the material in which you are interested.
Pay attention to the date of copyright, if provided. There may not be an owner of the copyright of a work, in some instances. According to Roger Pearse on tertullian.org, the following are out of copyright: material published in and before 1922; and between January 1, 1923 and December 31,1963 unless the copyright was renewed. For more information on copyright expiration, called transition to public domain, see Resources for Cornell University's guide.
Use online resources to conduct research into existing copyright ownership. Visit the Online Books Page Catalogue of Copyright Entries at the University of Pennsylvania (see Resources) to access some online copyright renewal records.
