Adventures in Self-Republishing is a guide for authors who want to republish out of print books in print or electronically. It focuses mainly on converting printed copies of books into form suitable for republishing by scanning them and running the digital image files through OCR to generate files usable for self-republication. It describes options that depend on the format of the book, including whether or not it includes illustrations, how elaborate the type formatting is, and its use of reference citations. It explains the important differences among the major approaches to self-publishing: on paper using print on demand technology, and electronically using either PDF format or e-reader formats used by dedicated e-book readers. It explains the advantages and disadvantages of each republishing format for various types of books. The author speaks from experience in having learned the hard way what works and what doesn't. He also describes the types of services available to help authors republish, and the trade-offs involved.
