book publishing simply refers to commercially producing a book and distributing it so that other could gain access to your writings and can read them. These also include audio books which most prefer. The expense of publishing the book is borne by the publishing company and is recovered once the book begins to sell. Most publishers face a lot of risk when it comes to publishing a book, since it is upto the editor to foresee if the books will sell well. If not the loss is borne entirely by the publishing company. Before distributing the books for sale it has to go through the process of manuscript or conception, production and marketing and sales and distribution.
