I had thought that Calibre was useless for my needs at one time & so deleted it.

Then the lightbulb turned on when I tried to read an epub on the same device using a different ereader app that doesn't do DRM; wasn't able to read the book on the same device residing in the same place. After some cursing, got Calibre again & reinstalled & also installed the drm removal. Will be using Calibre to remove drm as my ereader app of choice is now Moon+ Reader Pro which doesn't do drm & may it never register as a drm app.

Another thing was that I found that having multiple drm registration is OK; BUT the problem is that it is NOT OK to have the device, ereader app, to have multiple drm IDs. This was the case where I have my tablet under a different email ID from what I was using for the public library which came first.

Removing drm is not only for sharing but for personal use with an ereader of choice.
