Adding to what others have said, I got Calibre-Web Automated set up and put KOreader on an old Kindle, so that when I find a book I can just upload it to CWA and easily browse the home library from my device (it sync progress too if you read on multiple devices).
You can also use calibre (desktop version) to strip DRM from library books so you can return the them earlier for someone else to borrow :)
