Wikipedia
Self-publishing is the publication of any book or other media by its author without the involvement of an established publisher. A self-published physical book is said to have been privately printed. The author is in control of the entire process including, for a book, the design of the cover and interior, formats, price, distribution, marketing, and public relations. The authors can do it all themselves or may outsource some or all the work to companies which offer these services.
Self-publishing is not limited to physical books. E-books, pamphlets, sales brochures, websites, and other media are commonly self-published.
