It seems like there are a hundred books on publishing and many more on book marketing.
The problem with these books is that they treat publishing and marketing as two completely separate concerns. Their thinking seems to be, ‘after your book is published, grab a book on marketing, read it and start doing it’. The reality of the publishing world is that the marketing has to be done in conjunction with the publishing. That means if you ignore the marketing until after you publish the book you’ve lost valuable marketing time.
My newest non-fiction project is called (so far!) How to Self-publishing and Market a Book. It’s a comprehensive guide to an integrated approach to self-publishing and marketing a book.
I’m about 2/3 of the way through the first draft and I have a street team reading through it to tell me what confuses them.
I’ve tentatively scheduled it for release in the fall.
