Another excellent if un-hearlded reference is to simply the Help files and sample databases. While the jargon (Ms. Speak) can be a bit daunting, most of the third party stuff is not much better and (possibly) a bit more expensive. A large part of the 'learning curve' for many is just to know the basic functions, but some time spent in just browsing the topics in the index goes a long way toward overcomming this and providing a decent intro.
As far as I know, this applies to most of the Ms. Speak languages and their docs.
