You cant go far wrong with the Oxford Dictonary of Philosophy, if your able to pick up a copy of it. Though if your new to Philosophy a dictionary may be not the best way to introduce yourself to the subject, but there are certainly very useful if you need to clarify some of the terms you come across when reading Philosophy.

What would be the best philosophy dictionary for a novice? I've had no exposure to philosophy in school, high school or college, and I'm venturing into it after studying mostly history and theology.

Strolling through a bookstore, I saw one by Penguin press, but upon searching through abebooks, there's a whole bunch of them (Peter Angeles' and Antony Flew's for example).

Stanford is number one free and online.

After that I'd recommend Routledge Encyclopedia of Philosophy. If you're a patron, some public and academic libraries have access to the online edition, but if not, the public library might have the print version in shelf.

I have a copy of the Routledge Encyclopedia of Philosophy and would have to agree that it is a rather good resource and covers any topic you could wish to know about. It is a rather epic encyclopedia though so be warned in that regard. The Oxford Dictionary of Philosophy is certainly good if you just want to look up a particular term while reading a work of Philosophy. I also agree Stanford encyclopedia is a good resource, but you might not wish to have to go online, everytime you wish to know something.
