Public Domain
Public domain is defined as a body of intellectual endeavours unfettered by law. [1]
Definition
Definition and problematic of the public domain: “The public domain is a space where intellectual property protection does not apply. When copyrights and patents expire, innovations and creative works fall into the public domain. They may then be used by anyone without permission and without the payment of a licensing fee. Publicly owned national parks are also considered by many to be public domain lands. Because of the extensions of the terms of both copyrights and patents, and the privatization of lands and other resources owned by the Federal Government, little is now entering the public domain. Since the public domain is a treasure trove of information and resources to be used by future generations, many advocates are concerned that its stagnation will make it more difficult for future generations to find creative inspiration."

Discussion
The public domain and the Commons
"If public domain can be considered a container, then the commons represents its content of inexhaustible resources, jointly held and accessible without permission." [2]
Most of the time, both concepts are used interchangeably, though the Commons seems to overtake the Public Domain in terms of popularity. The public domain concept relates the 'outside' of the intellectual propery system, i.e. items without copyright, and thus stresses the open access features: nobody can be excluded. The Commons stresses the absense of state, corporate and individual control, in favour of distributed control, and is related to non-private and non-state common property regimes.
For an investigation of the differences between the concepts, see the essays by James Boyle, at http://www.law.duke.edu/pd/papers/boyle.pdf (The Second Enclosure Movement and the Construction of the Public Domain) and http://www.law.duke.edu/boylesite/foreword.pdf (The Opposite of Property)
The Public Domain and U.S. Copyright law
Wikipedia states that
"Robert A. Baron argues in his essay “Making the Public Domain Public” that “because the public domain is not a legally sanctioned entity,” a statement disclaiming a copyright or “granting” a work into the public domain has no legal effect whatsoever, and that the owner still retains all rights to the work not otherwise released. The owner would then have the legal right to prosecute people who use the work under the impression that it was in the public domain. It is certainly true that under some jurisdictions (which ones?), it is impossible to release moral rights, though that is not the case in the United States. A more likely problem may be the lack of factual evidence that the owner has indeed put the work into the public domain.
Some scholars of copyright law, including Lawrence Lessig, agree that it is difficult to put works in the public domain, but not impossible. The Creative Commons website, for example, has a public domain dedication form which produces an electronic receipt which is meant to act as legal backing for the dedication. Even if it is ruled that a work cannot be released into the public domain, a thorough dedication such as this one also releases all rights, so that the author retains only a free-use license. Lessig, however, argues that another licensing option, such as the Creative Commons Attribution-Only license, is a safer choice, and that click-through agreements are insufficient to put works in the public domain."

St. Peter explains what needs to be done at https://stpeter.im/?p=1780:
"1.American law was modified in 1976 to automatically put works under copyright, thus (seemingly) removing the option to place one’s works directly into the public domain. This change supposedly protected creative individuals but in fact restricted their freedom.
2. The identity of the author is not necessarily clear from a legal perspective. Yes, I own saint-andre.com (look it up in whois), so presumably I have control over what is posted at that domain. But is my assertion that I am the author of, say, Who’s Afraid of the Public Domain? legally binding? Well, it appeared at my website first, but it’s not digitally signed, so who knows.
To overcome some of these challenges, Creative Commons provides a public domain dedication service whereby the author enters an author name, email address, and work title into a web form and Creative Commons sends an electronic receipt to the author and to Creative Commons. But who says that a given email address can be reliably associated with the author? A stronger method would involve the use of digital signatures, but that is prohibitively difficult for the average creative individual, who doesn’t know what a digital certificate is, let alone have the tools that would make it easy to digitally sign documents, images, and the like — heck, even I don’t know how to digitally sign an HTML file with OpenSSL, and (thanks to Thunderbird) I digitally sign the email messages I send!
It’s clear to me that we need better tools to enable rights-assignment (including assignment to the public domain) during the authorship phase — support in word processors, desktop publishing programs, image creation applications, music recording software, and so on. We need better ways to associate electronic files with authors, whether through digital signatures or some other means. We need ways to register public domain works with a neutral third party such as Creative Commons. Then we need to start testing these mechanisms among authors and in the courts of law and public opinion." (https://stpeter.im/?p=1780)
