Librivox recordings

Hi Steve,
I have been using a number of Librivox lessons in German here on LingQ. These have been most helpful to me. Thanks to those who imported them.
I have also imported a number for my own personal use. Is it permitted that we import them for general use? Do we need to ask permission for this?

We are allowed to use librivox recordings.

Perhaps a rule of thumb could be: if a Librivox story helps you, then it will probably be useful for other LIngQers, so it would be good to share it on LingQ.
