Well let me count the ways!
Distribute Your BOOKS
By yourself - This has got to be the hardest ways to sell books. But even I do it a little. When I have request for signed books, they come from the bookshelf in my house where I have at least ten books of each that I've written. But there are other authors that house many more printed copies of their books and fulfill orders out of their home or storage areas to mail off to buyers.
Use A distributor - I use Bookmaster, a friend of mine uses IPG and there are tons of other distributors that support small independent publishers and even self-publisher by making their books easily accessible to Bookstores, Libraries, Createspace, Lightening Source and other retail venues. For ebooks, I also use Smashwords, Bookbaby, Amazon, B&N, iTunes and many more.
