Consistent research sources management. No hidden fees. Nice UI.

Probably the best open source alternative to Endnote, even though it does lack some functionality. Most notably, it lacks the ability to make composite references (ie reference 1 a)... b)... c...). However, from a privacy perspective and the fact that its excellent browser plugins can save information conveniently, it's still highly recommended.
