So I have way more books on my e-reader than I can keep track of these days, thanks mostly to BookBub, which means that after I finish one book I have to decide which one to read next. I could do something normal like have them in a first-in-first-out queue, but that would be too easy. So instead I use Calibre to help me pick a new book after I finish one. Because I’m random that way.
