The ASA has compiled a compact PDF booklet with practical advice for self publishers. Of particular note is their discussion re. pricing a book by factoring in production, distribution and bookstore costs, and a rather short list of distributors who may be willing to take on self-published authors (especially those with active promotional plans). The Arts Law Centre of Australia has also compiled an in-depth discussion of self publishing from their rights/legal perspective.
Printed books seem have unexpected staying power. The growth of the ebook segment of the market has slowed dramatically, and independent bookstores have experienced a modest expansion, both in terms of the number of stores and overall sales. Readers cite the tactile aspect of the printed word, along with the aesthetics of a good bookshelf. Not that the digital revolution hasn't changed the book trade — at least 40% of all book sales are now online.
