Calibre is a great, free program that converts and sorts ebooks. I often use it to sideload ebooks to my nook.
Great side for E readers, it allows you to better interface with your reader; as well as do conversions.
Simply amazing. The best program for reading/converting/managing/etc eBooks. It's light, fast, and easy. It can open various file extensions (.lit, .pdf, .epub, .mobi, and like a hundred others - most of which I've never even heard of; surprisingly, it apparently can open ZIP/RAR/etc files, although I haven't tried it), although you can specify whether you want to use the internal viewer (which is great) or some other program for each extension. It has a customizable viewer (font size, which most surprisingly don't have the option, except for Calibre). Some features are even better than Adobe Reader (although it doesn't have Adobe's incredible bulkiness). It's even open source (meaning it's free, and developers can view the code, if they want).

One of the best free apps for reading e-books. It helps you to keep your personal library in order.

I have heavy filters and heavier malware protection. When your career rests on the files and notes on your laptop you better be sure when you download programs that you are not going to lose everything. This so far has passed my expectations of safe secure user friendly usage. I will update if it no longer appears to be as safe in the future as it is now.
a good and secure site
Warning! Some of the devs on this project are incompetent regarding security: Don't install Calibre if you value the security of your computer.
