File management does not seem to be a one-size-fits-all proposition. Thus, while general-purpose file managers exist, it often appears that much of the development effort goes into domain-specific management tools. We have a whole set of photo management applications, for example, and even more music managers. When it comes to electronic books, though, there seems to only be one viable project out there: Calibre. LWN last looked at Calibre almost exactly two years ago. The recent version 1.0 release provides an obvious opportunity to see what has been happening with this fast-moving utility.
