Open Access (OA) movement has changed the way of scholarly publishing. Based on free, unrestricted online availability of scholarly communication, it has existed since the early 1990s. It has strongly influenced accessibility and impact of scholarly communication in the last quarter-century. OA advantage is proved by many researchers, e.g. Harnad, Altman, Moed etc. OA can be achieved in two ways, through OA repositories and through OA journals. In the scope of this presentation are OA journals. At the beginnings, freely available scholarly journals were edited and published by enthusiasts who wanted to prove that publishing high quality scholarly information can be cheaper and faster in electronic environment. They worked for free and the first OA journals were completely freely available, with no costs, either for users (readers) or for producers (authors) of scholarly papers. Today, it is obvious that there are some costs in OA publishing that have to be covered.
