It is easier to choose a publishing partner when authors know their priorities. Some authors may need assistance from a professional editor; others may need only formatting and design, distribution, or promotion help. Any decent publishing partner will evaluate such needs, offer some publishing packages, and clarify what is included and what kind of results should be expected. One may also learn how consistent a team of professionals is by looking into portfolios, testimonials, processes, and contracts. If an author is looking for a systematic approach to publishing his work, then a book publishing company will arrange for specialist assistance while staying in touch all along.
