This principle leaves full freedom for authors to distribute their work in other ways without needing consent from a third party.

There are no publication charges as long as the amount of submitted data can be handled by the Publisher within the technical limits of the Journal.
Reprints are avaiable at production cost.
The descriptive part of the published manuscripts is reprinted on paper in the form of Proceedings volumes.
