The site Buddism Tour offers a broad range of information on all aspects of buddism, some on hinduism as well.

Wikipedia is the free encyclopedia on just about any subject you want. The link provided here is for the general over view of Buddhism and links to the various forms. I have found the site to be enlightening but as with everything you must take it as a grain of salt and allow your soul to guide you in your findings.
