Traditional publishers refer to publishing companies that have been in existence for a long time and follow conventional methods of book production, distribution, and marketing. These publishers typically work with established authors or those who have already built an audience through self-publishing or other means. They provide services such as editing, cover design, printing, and distribution to the author in exchange for royalties or a percentage of sales. Traditional publishing is often considered more prestigious than self-publishing because it involves a vetting process by industry professionals who determine if a book has potential commercial success.
