Bulfinch's Mythology
An old standard and classic reference for the stories about gods and heroes.  Often includes references to other poetic works that allude to the characters of Greek mythology.  Stories here are told like a story and make for a much more fun and interesting read than the more encyclopediac references above.

Greek Mythology Link - by Carlos Parada
This is an amazing site with thousands of cross-linked references, incredible art and citations of the literary references relevant to each character and story.  Parada uses the transliterated forms of the Greek names, which are not always spelled in a familiar way.  However, the value of this site is immeasurable, and it will provide a useful, detailed point of reference for any student of the Classics, from beginners to professionals.
