Which Version of EndNote Should I Use?

EndNote releases a new version of its desktop software every year and it can be difficult to decide if it's worth upgrading from an earlier version. This year EndNote X3 for Windows was released in June and X3 for the Mac in August. I haven't got a copy of X3 yet but from what I've heard it's fairly similar to EndNote X2.

The University of Queensland has a great review of X3 features.

Mac users should note that EndNote X3 will run on OS X (10.5.6) but there are reports of problems with Snow Leopard, the latest Mac OS release.

EndNote versions X, X1, X2 and X3 seem to be fully compatible with each other. However, if, for example, EndNote X users open a library created in X3, new features only available in X3, such as groups, are ignored by version X. Otherwise all the key features are the same and if you take a class using X2 you won't have any problems using X3 or X1.
