Before you simply Google "Aristotle" and click on the first link that comes up, try these resources:

• Stanford Online Encyclopedia of Philosophy (SEP) - this is a searchable online philosophy encyclopedia written by experts in the field. Most entries conclude with a bibliography of relevant works, both online and in book/article format.
• Internet Encyclopedia of Philosophy (IEP) - like the SEP, the IEP is peer-reviewed and includes articles on philosophers and philosophy topics.
• EpistemeLinks - this website includes a database of excellent philosophy links, including e-texts of philosophical works and pages of knock-knock jokes!
• Wikipedia.org - this Internet standby is generally acceptable for philosophy topics, although unlike the IEP and SEP, it's best to use it as a way to get a very broad overview and then find more specific links.

So you've started to read some philosophy. That probably means you have some burning questions. What is das sein? Just who is Kripke's Wittgenstein? Here are some places where you can find other people to talk to about these topics:

• Blogs, blogs and more blogs! - many philosophers and philosophy graduate students have blogs where they post reflections on what they are reading as well as their own idea. You can find some of these blogs at the Academic Blog Wiki, as well as the EpistemeLinks website. There is also the Philosopher's Carnival, which pulls together the best of the philosophy blogosphere each month and is hosted by Richard Chappell of the blog Philosophy, Etc.
• Philosophy Forum is one of the many online forums you can join to talk about philosophy. Ephilosopher and Philosophy Forums (note the plural!) are two others. Look through the forums to see which threads and categories are most active--if you're interested in philosophy of mind and most discussion centers on ethics, this isn't the forum for you! Also look for how carefully moderators toss out flamers and spammers. Is the discussion centered on philosophy, or is it bantering about one's personal opinion?

There are also resources online where you can not only discuss philosophy, but hear free lectures from professional philosophers! Why pay for a course when you can listen to podcasts?

• Philosophy Talk - this podcast from Stanford University bills itself as the show that "questions everything, except your intelligence." There is an annual fee to download the podcast ($9.95 monthly/ $69.95 annually) although older versions can be found free on iTunes. The hosts of the podcast are both philosophy faculty at Stanford University and generally provide lively, easy-to-understand commentary as well as interviews with famous living philosophers.
• The Philosopher's Zone - a radio program from "Down Under" with Alan Saunders, this podcast is similar to Philosophy Talk,except that free transcripts are available online. It airs weekly and includes a wide range of topics, from slavery to Buffy the Vampire Slayer to Eastern philosophy and more.
• Philosophy Bites - the hosts of Philosophy Bites are David Edmonds, a documentary producer for the BBC and Nigel Warburton, a lecturer in philosophy in the UK. Listening to their "classics" section would give a good introduction to philosophy, although they, like the other podcasts, have done programs on more contemporary topics such as torture, slavery, etc.
• Podcast Clearinghouse at Learn Out Loud - to find these, and other, podcasts related to philosophy, you can go to LearnOutLoud.com and search. Click on the link to go directly to the "philosophy" topic.
