Nevertheless the books seem to be published by many publishers, the truth is a bit different. All but the last one follow the same editor, Vlado Ríša, who had been a publisher (publishing house Golem Ríša), but becouse of private reasons decided to stop his own publishing activities and started to work for larger publishing house Mladá Fronta. That is why two books are published by this publishing house. When Vlado has left Mladá Fronta, I have started looking for new publisher, and it is Straky na vrbě. The cooperation seems to be fine and I hope that many other books from the world of Wetemaa will be published by Straky na vrbě.
