The music industry has already undergone a complete restructuring - now digitalization has also reached the book market. For a long time, there was no way around a publisher. Now, flexible business models such as self-publishing and print-on-demand offer entirely new opportunities for book publishing and marketing. The formal boundaries between authors and readers are being dissolved and replaced by flexible, direct communication structures. The epubli Book Marketing and Social Media Guide aims to serve as a practical roadmap for authors navigating the growing diversity of distribution and marketing options. In addition to a wealth of information on book marketing, it provides an overview of the specifics of social media and highlights what to consider when creating a book. Furthermore, it explains the tools and success measurement of online marketing.
