Yesterday I read about the prices that a major publisher charges to publish a paper as open-access. It is a whoppy 3000$. The authors then retain the full copyright. The publisher probably will make the paper available online on its server and take care that it is included in various bibliographies. The publisher probably also taken care of the long-term archival, which CEUR-WS.org currently cannot do.
But compare this to what we charge: 0$
Certainly, we do have costs that we do not charge such as our own work time and the costs for keeping the server online. But how can someone justify 3000$ for something that we offer for free?
What would you regard as a fair price?
Quo vadis CEUR-WS.org?
