The main theme of this year's festival is "Microcosmos", a reference to Pula and Istria.
The fair will feature over 120 authors from all over the world.
In attendance at the opening ceremony will be Croatian Culture Minister Nina Obuljen Koržinek and Rob Riemen, a Dutch philosopher, writer and the founder of the Nexus Institute. Riemen, who rose to international fame when his "Nobility of Spirit" book was published, has written an essay about Pula, too.
Over 30,000 titles published by over 300 publishing houses from Croatia and its neighborhood will be included in the fair.
