Open Access funding is an extremely important question, however hardly mentioned in Polish literature. The Open Access model, assumed to assure free access to resources, generates system, organizational, and administrative costs, which we shall be aware of. The author discusses current methods of Open Access publications' funding, like: author, institutional, double, shared, and hybrid models, as well as governmental funding, grants, and payable membership in an OA publishing house. Particular attention is put on an author model of financing OA publications, assuming that costs of publishing texts are paid by their authors. The levels of authorship fees in most of commercial OA and hybrid journals' publishers are described.
