What Kallipos is
Kallipos is a free web repository for electronic textbooks, mainly serving students and professors at Greek universities. Founded in 2013, it makes every repository book available to download in full under open licenses, either as a complete volume or as separate chapters. Most titles are educational, and many are recommended by teachers for courses. Readers can use PDF, EPUB, LaTeX, and DocBook formats; books carry ISBNs and EUDOXOS codes. Kallipos also provides an authoring and publishing workflow. Authors submit proposals through open calls or offer finished digital books, which the Scientific Coordination and Evaluation Committee reviews with external evaluators. Approved manuscripts receive linguistic and technical editing before upload. A web registration platform handles member roles, proposals, evaluator assignments, monitoring, and reports. Eligible registrants include university faculty, researchers, freelance scientists, and PhD or master’s degree holders. KALLIPOS+ support is available through a dedicated platform or email.
