Many self-publishers are choosing on-demand publishing as their preferred publishing method. Although many on demand publishing services can be expensive for a single copy, this is not as costly as paying for the storage of thousands of books published the traditional way. On-demand publishing can be a cost effective option for self publishers who only need to print the number of books they have orders for. Another use for this type of technology is to re-release books that are now out of print. This allows authors to bring their books to the attention of a new audience.
