<P> With respect to governmental information, any government may distinguish which materials are public or protected from disclosure to the public . State materials are protected due to either of two reasons: the classification of information as sensitive, classified or secret, or the relevance of the information to protecting the national interest . Many governments are also subject to sunshine laws or freedom of information legislation that are used to define the ambit of national interest . </P> <P> The United Nations' 1948 Universal Declaration of Human Rights states: "Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference, and to seek, receive, and impart information and ideas through any media regardless of frontiers". </P> <P> This philosophy is usually accompanied by legislation ensuring various degrees of freedom of scientific research (known as scientific freedom), publishing, and press . The depth to which these laws are entrenched in a country's legal system can go as far down as its constitution . The concept of freedom of speech is often covered by the same laws as freedom of the press, thereby giving equal treatment to spoken and published expression . </P> <P> Freedom of the press is construed as an absence of interference by outside entities, such as a government or religious organization, rather than as a right for authors to have their works published by other people .

If the author cannot reach a voluntary agreement with a publisher to produce the author's work, then the author must turn to self - publishing . </P>
