Bookselling is the commercial trading of books which is the retail and distribution end of the publishing process. People who engage in bookselling are called booksellers, book women or bookmen. The modern system of bookselling dates from soon after the introduction of printing. A bookseller is a person who sells books, especially as the owner or manager of a bookshop. Modern book selling has changed dramatically with the advent of the internet. With major websites such as Amazon, eBay and other big book distributions offering affiliate programs, book sales have now, more than ever been put in the hands of the small business owner.
