I have a large ebook collection which I like to be able to access over the internet from any device. I tried quite a few ways to do this before settling on an App called Calibre-Go. This seems to work pretty nicely for my needs but I wondered what others were using . What it involves is storing your Calibre library online in a cloud storage service like Google Drive, OneDrive or Dropbox. You then insall Calibre-Go on your phone or tablet and once you have pointed it at your Calibre collection it syncs so that you browse you r entire collectionn pretty effectively including seeing all the Covers, Reviews, Metadata etc. . If you want to read a particular book you can then just click to download to your device and read in any of the ebook reader aps ( I use Moon Reader).
Does anyone else use this or an alternative system?
