Hello,
I open this thread to present you a Web interface for Calibre.
This one works on the same principle as COPS:
Have a Calibre bookcase on a Web server (as a NAS) and be able to consult it since a web application without Calibre server.
This interface is to be considered as a complement to COPS: My Readings requires devices a little bit powerful as an iPad but allows, in return, a more optimized browsing.
A pesentation and the instructions for the installation are here:

The page is in French but My Readings can be multilanguages (at the moment, in French and in English).
A demo:
