The open-source ebook management software Calibre has hit version 3.0 after years of development.
Calibre is one of my favorite open source programs, it's a very powerful way to organize your ebook collection. If you have a big collection like I do, it's almost a necessity.
I'm pretty excited about this one, as it includes a rewrite of the content server. This means you can connect to your library and read your books anywhere, even on mobile devices. Looking forward to future updates!
