Public domain: The term public domain has two senses of meaning.  Anything published is out in the public domain in the sense that it is available to the public.  Once published, news and information in books are in the public domain, although they may also be copyrighted.  In the sense of intellectual property, works in the public domain are those whose exclusive intellectual property rights have expired, have been forfeited, have been expressly waived, or are inapplicable.  For example, the works of Shakespeare and Beethoven, and most of the early silent films, are all now in the public domain by either being created before copyrights existed or leaving the copyright term.  Examples for works not covered by copyright which are therefore in the public domain, are the formulae of Newtonian physics, cooking recipes, and all software before 1974.  Examples for works actively dedicated into public domain by their authors are reference implementations of cryptographic algorithms, NIH's ImageJ, and the CIA's "World Factbook".  The term is not normally applied to situations where the creator of a work retains residual rights, in which case use of the work is referred to as "under license" or "with permission".

In 2015, GitHub reported that approximately 102,000 of their 5.1 million licensed projects (2% of licensed projects on GitHub.com) use the Unlicense.

Public Domain Mark: Public Domain Mark (PDM) is a symbol used to indicate that a work is free of known copyright restrictions and therefore in the public domain.

The Oz books of John R. Neill, Rachel R. Cosgrove, and Eloise Jarvis McGraw and her daughter Lauren are all protected under U.S. copyright, making their characters and developments unusable by others without permission.
