Hey Kjartan, nice to see you writing packages and contributing to Emacs now.

This sounds interesting indeed, but it would be nice if you could add some
(more) explanation about the
 package in the repo its README and/or in the initial comment of the
calibre.el file.

Also, I am using the very mature calibredb.el
<https://github.com/chenyanming/calibredb.el> package for a few years
already. Are you already aware
of its existence? If so, besides that that package is only available from
Melpa, could you explain why you
wrote this similar alternative package?

Anyway, thanks for sharing your package! And nice job!
