Aristej started as a publisher of children's books in 1993 and with the integration of Dialogi Journal next year re-established itself as a publisher of social science and humanities books. Since 1998 it publishes the magazine Dialogi Journal, and since 2007, the Analiza Journal. They have continued to translate and publish books for children, and started with the collection of educational books for youth called "Pojmovnik" ("A Glossary"). Many of Aristej’s books have opened up new fields and topics which prior to that time had not been treated in Slovenia so comprehensively, especially in the field of analytical philosophy. Some of the books can be bought online.
