Moon builds its own database as books are opened or added to its shelf, which is how i like it - just a few in progress books. I wish there was a good way to remember the spelling, I constantly muddle it you simple enable calibres' built in content server and that delivers OPDS / ODPS whichever is correct. You don't need any cloud services/servers. With that being said, if I install mi files from Calibre to the device (memory or SD card) or sync the library to the SD Card, will Moon+ Pro be able to use Calibre metadata to search, sort or filter the eBooks using (say) title, author, tags and series? I haven't got access to cloud services/servers that would allow me to use Moon+ Calibre OPDS server connection.

On Moon+, you go to Net Library > tap on the 3 dots on upper right corner > Add new catalog > Calibre IP Address to the feed would just have opds at the end: It's built-in to the Calibre content server. If you are stuck I will look up what OPDS settings I have in moonĮdit - here from the other thread, I have a bad case of dyslexia when it comes to that server Instead, i used a library copy in dropbox and the app called calibrebox from play store, for when my library pc is off ( because cc cannot authenticate with dropbox on a new tablet) I put pcloud onto my tablet and copied my library to pcloud but CC can't find that. The SD card think should also work, but not a virtual drive e.g. you basically have to add OPDS to the end of a URL and point moon at it

There are threads somewhere ( in CC subforum) with how to do it - I used them myself. its almost as as good as going via the app.

Moon reader can directly connect to calibre OPDS server.
