Discover India: The Indian Government's Ministry of External Affairs' site: culture, tourism, economy, social issues, nuclear policy, a Gandhi retrospective (p.s. see the movie 'Gandhi' before you even think of going), even a quick summary of Hinduism.

The Hindu national daily newspaper (which by some amazing fortune my friends and I made the cover of in a story about Semester at Sea and the visiting international students.)

The History of India: a well-done site with timelines.

India Tourist Information: maps, hotels, food, travel, events, etc.
