Public domain

From RationalWiki

Public domain refers to information, data, textual or musical work that is freely available for copying and distribution. In broad terms, works that are not covered by copyright, patent or other form of legal protection are considered to be in the public domain and may be accessed, used, copied and distributed by anyone.

Since copyright and patent laws vary from nation to nation, what is or is not public domain can be confusing. Most of the contents of Project Gutenberg, for example, are in the public domain in most countries; however, due to differences in copyright regulations across national borders, Gutenberg Australia, though related, has much material that is in the public domain in Australia that is still covered under United States copyright. (Remember to consult your local copyright authorities before loading up on George Orwell bootlegs.)

Much software, including many free software packages and virtually everything produced by the United States government (see ImageJ for one example, a high-quality image editing program written in Java), is public domain; however, most freely distributable software is copyrighted, usually under an open source license that asserts the creator's copyright while explicitly giving the user many, but not all, of the rights associated with public domain distribution.

According to Andrew Schlafly, anything he wants to copy to pimp out his blog is "public domain".
