EPIC, the Electronically Published Internet Connection, is a professional organization for published and contracted e-book and print authors. It was established to provide a strong voice for electronic publishing.
Even though E-Publishing is a relatively new venue, there are many readers, writers, and traditionally published authors who believe this is one of the major marketplaces of the future. EPIC exists to help professional writers learn more about the best publishing opportunities on the Internet and to provide networking opportunities for exchange of information about promotion and market growth.
