A book publisher is a group or person who is responsible for bringing the book to the public for reading purposes. The book publisher is involved in the major steps of developing, marketing, producing, printing, and distributing the book. The book publisher negotiates with authors over intellectual property rights, rights to distribute, and rights to change the book. The publisher also offers the author a bonus, royalties, or a percentage of sales. See self-publishing-steps.com for the steps required to publish a book yourself.
