This is bad advice. Using Calibre while knowing that certain circumstances surrounding a network disconnect might corrupt your library database is better than rejecting Calibre out of hand since it doesn't support network libraries well.

Best of all would be in Calibre's library handling weren't so finicky, but in the absence of that, I use Calibre with a remote share and I'm just very careful about library backups, how long I leave it running, and am patient with the slowness.
