What Kallipos is

KALLIPOS is a Greek university textbook project and digital repository where readers can download complete books at no charge under open licenses. The collection is mainly educational and offers books as full volumes or independent chapters. Supported formats include PDF, EPUB, LaTeX and DocBook, and many titles are recommended by teachers for their courses. Books have ISBNs and EUDOXOS codes and are included in relevant directories. KALLIPOS also supports book production: authors can submit proposals through open calls or offer finished digital books, and the Scientific Committee evaluates submissions. Approved manuscripts receive linguistic and technical editing before they are uploaded. Its web-based Registration and Administration Platform supports members and external collaborators with proposal administration and evaluation workflows. Registration is required for project roles; eligible registrants include faculty, researchers, scientific associates, freelance scientists and people with PhD or master’s degrees. The project began in 2013 and is funded through Greece’s Public Investment Program via the Ministry of Education and Religious Affairs. Its 2026 extension includes updates, translations and EPUB3 editions.
