Traditional publishing companies are entities that produce, edit, and distribute content for authors, usually in print or digital format, for a fee. These companies assess the author's work to see if it is suitable for publication and to ensure that the book has a strong chance of success. This vetting process includes conducting editorial assessments of the work, printing, editing, and marketing the book. Traditional publishing companies are generally considered to have the most credibility and hold the greatest power in the publishing industry, as they are often staffed by industry professionals and have a large network of readers and potential customers. A traditional publishing company may also offer authors a variety of services such as editing and marketing, as well as in-depth knowledge of the publishing industry.
