Self-publishing is a spectacular phenomenon showing how the electronic book creates a paradigm shift. Information technology makes it possible for authors to upload their work to a bookshop and decide how they will be published. It is the author who decides about the price tag, the distribution location and the key formatting features of the book. The books are published with POD (Print on Demand) methodology, as well. The circulation does not determine the retail price, it is possible to print even just one copy. The books at Publio are personalized, the customer decides about the sophistication level of the print: such as the title page quality or whether illustrations should be in colour. Another Publio division is the digital service for publishers. Publio is the most significant partner of Apple, therefore it may publish and distribute titles directly in the iTunes Bookstore. Publio can count important publishers as its customers, more than ten at the time of writing. Publio is also the most significant partner of Smashword, the number one self-publishing global portal. Therefore all Publio books will be published via the Smashwords distribution to the best known e-book sites: Sony, Kobo, Barnes and Noble. Publio has a direct partnership with Amazon for the distribution English language books published.
