I also edit metadata as soon as books are loaded into Calibre. I edit author, title etc and add series info. I don't use plug boards as I email the most important books I want to read to my Amazon cloud but I do keep both mobi and ePub format of my books in Calibre and my library resides on Dropbox with three laptops pointing to the same library. I use tags extensively that's how I keep my books organised. And hubby's as I manage all the books myself. He won't do anything in Calibre other than enquire
