Self-publishing has transformed from a niche alternative to a mainstream route for authors seeking control, speed, and higher royalty potential. It encompasses a suite of services and choices—manuscript preparation, editing, cover and interior design, formatting, distribution across print-on-demand and e-book platforms, marketing, and rights management—that together let writers shepherd their work from draft to market without traditional gatekeepers. The business of self-publishing requires not just creative skill but also entrepreneurship: authors become project managers, marketers, and sometimes small-press operators who must balance quality, cost, and visibility.
