What are good internet resources for research in Indian philosophy? Here are a few that come to my mind.
The GRETIL project of electronic Sanskrit texts: http://gretil.sub.uni-goettingen.de/#Intro
The Monier Williams Dictionary online: http://www.sanskrit-lexicon.uni-koeln.de/monier/
The Internet Encyclopedia of Philosophy, whose Indian Philosophy section is edited by our own Shyam Ranganathan: http://www.iep.utm.edu/category/traditions/indian/
The Stanford Encyclopedia of Philosophy, whose Indian and Tibetan section is slowly being built up, edited by Jan Westerhoff, Jay Garfield, and Jonardon Ganeri: http://plato.stanford.edu/search/searcher.py?query=indian
Karl Potter’s bibliography–updated regularly–to the Encyclopedia of Indian Philosophies: http://faculty.washington.edu/kpotter/
