Thanks for the first replys. I guess, there are some missunderstandings.

First, if I start Calibre-GUI, create different librarys and then start the internal server, you can choose the used library after login to the web page (see attache).

I want to create this behaviour using the command line by using the calibre-server.
But the calibre-server cli didn't use the multiple librarys from command line.

And sorry, I didn't find this inside the manual.
