A traditional publisher is a publishing company that works with authors to produce and release books, magazines, or other printed material. Traditional publishers usually take on the majority of the production costs associated with a book, including editing, printing, and distribution. In exchange for this investment, traditional publishers typically retain the majority of the book's royalties and control over its publication.
While traditional publishers have been in operation for hundreds of years, the advent of digital publishing has made it possible for authors to bypass traditional publishers altogether and release their work directly to the public. This shift has led to a drastic increase in the number of self-published books in recent years.
