Authors can publish their own books using print-on-demand and e-book technology. Many authors choose self-publishing over traditional publishing because it provides them with greater control over their work, and the authors receive all the profits.
With traditional publishing, the publisher covers all the expenses, but the author only receives a small percentage of the profits. Authors who self-publish have to pay all their expenses, but they receive all the profits.
E-book technology is a very popular option that allows authors to sell and distribute their books electronically with no up front or per-book publishing costs. Self-publishing tools are available from some e-book sellers, such as Amazon.com and Barnes & Noble. With print-on-demand technology, books are only printed when they're ordered. Which method is better depends on the author and the type of published work.
