A search of Google groups reveals that the issue of OS X bibliographic
management software hasn't come up in some time.
Specifically, I have tried using EndNote and BookEnds on OS X, and like
both for different reasons: outstanding sup****t and integration with
Mellel from BookEnds, and industry standardization (positive and
negative) in EndNote. EndNote was sluggish on my machine, and I ended
up getting a refund for the product and returning it. I'm switching to
BookEnds.
What are your opinions on the state of OS X bib managers and which
products are you using/recommending?
