My reactions to this is exactly that of  Joyce Valenza's.  I teach citing and evaluation using EasyBib, and demonstrate to students that  the need to check the automatically filled in  spaces for accuracy gives them a chance to evaluate sources credibility for themselves, as they look for who really belongs in Producer/Sponsor slot.

Noodletools

Noodletools  http://www.noodletools.com/ is one of the best values for schools out there.  They offer a free citation maker  that  produces correct citations. ( Some citation makers don't, alas).  Their subscription product has a wonderful notecard  module  that gives studnets a way to save their research and also make it their own.  Another great feature is the "sharing with teacher" whereby the teacher can make ongoing comments on a research project.
