Five years ago, the European Society for Traumatic Stress Studies (ESTSS) launched European Journal of Psychotraumatology (EJPT) (Olff, 2010). Knowing very little about the world of publishing and in particular about Open Access, it was quite an adventure! Somewhat idealistic, and after having been convinced that Open Access is the future publishing model, we performed a detailed search among potential publishers and found Co-Action Publishing, a relatively small Swedish publisher but with a great deal of experience in journals publishing and with a passion for Open Access.
