Public domain – in many countries this is legal term within the Copyright and Internet Law referring to works that are not copyright protected – i.e. being free for all people to use these without a particular advanced permission. This includes works that were originally non-copyrightable (items that by their very nature are not eligible for copyright such as ideas, facts or names), copyright that has been lost or expired, where copyright is owned or authored by the government (documents and publications are not copyrighted and so are public domain), and those works which have been specifically granted to the public domain.
