Publishing is the process of production and dissemination of literature or information – the activity of making information available for public view. In some cases authors may be their own publishers, meaning: originators and developers of content also provide media to deliver and display the content.

Traditionally, the term refers to the distribution of printed works such as books (the "book trade") and newspapers. With the advent of digital information systems and the Internet, the scope of publishing has expanded to include electronic resources, such as the electronic versions of books and periodicals, as well as websites, blogs, video games and the like.

Publishing includes: the stages of the development, acquisition, copyediting, graphic design, production – printing (and its electronic equivalents), and marketing and distribution of newspapers, magazines, books, literary works, musical works, software and other works dealing with information, including the electronic media.

Publication is also important as a legal concept: (1) as the process of giving formal notice to the world of a significant intention, for example, to marry or enter bankruptcy; (2) as the essential precondition of being able to claim defamation; that is, the alleged libel must have been published, and (3) for copyright purposes, where there is a difference in the protection of published and unpublished works.

The process of publishing

Book and magazine publishers spend a lot of their time buying or commissioning copy. At a small press, it is possible to survive by relying entirely on commissioned material. But as activity increases, the need for works may outstrip the publisher's established circle of writers.

Writers often first submit a query letter or proposal directly to a publisher according to submission guidelines or to a literary agent. Submissions sent directly to a publisher are referred to as unsolicited submissions. The majority of unsolicited submissions come from previously unpublished authors. When such manuscripts are unsolicited, they must go through the slush pile, which publisher's readers sift through to identify manuscripts of sufficient quality or revenue potential to be referred to acquisitions editors, who in turn refer their choices to the editorial staff. This process is dependent on the size of the publishing company, with larger companies having more degrees of assessment between unsolicited submission and publication. Unsolicited submissions have a very low rate of acceptance. Many book publishing companies around the world maintain a strict "no unsolicited submissions" policy and will only accept submissions via a literary agent. This shifts the burden on assessing and developing writers out of the publishing company and onto the literary agents.
