eBook readers been around for a while on various devices and platforms.
eBooks are easy to publish and distribute but now, with print-on-demand, paperback books are also an option.
In the past, self-published authors took their manuscript to a printer. Generally a minimum print run was around 50 to 100 books. Some of these could be sold to friends and family and the rest gathered dust in the spare room.
Now, with print-on-demand, authors no longer have to hound relatives to buy a book.
Instead companies like Blurb or CreateSpace print a copy only when there is a confirmed sale. This takes all the hassle and expense away from the author who need only sit at home and wait for a royalty cheque.
Having both eBook and print versions is a great way to increase your sales and leave your friends and relatives in peace.
