Having finished this book, there are three up-to-date books in particular that we would recommend for further reading in mainstream, Mahāyāna and tantric Buddhism. These three books mainly relate to the Buddhism of India and Southeast Asia, although the book on Mahāyāna goes well beyond that and will serve as a good introduction to Buddhism in China, Japan and Tibet as well:
Davidson, R. M. (2002a) Indian Esoteric Buddhism: A Social History of the Tantric Movement, New York, NY: Columbia University Press.
Gethin, R. (1998) The Foundations of Buddhism, Oxford and New York: Oxford University Press.
Williams, P. (2009) Mahāyāna Buddhism: The Doctrinal Foundations, Completely revised Second Edition, London and New York: Routledge.
If you wish to read some Buddhist scriptures, a good place to start is Rupert Gethin (2008) Sayings of the Buddha: A Collection of Suttas from the Pāli Nikāyas, Oxford: Oxford University Press.
Another easily available volume with Mahāyāna material as well, is: Lopez, D. S. (ed.) (2004) Buddhist Scriptures, Harmondsworth: Penguin Books.
After reading these books, the best way to widen your reading in the areas of Buddhism we have discussed here is to take up the books and articles referred to in the notes and references to the chapters that interest you.
The main website for Buddhist Studies is the Buddhist Studies WWW Virtual Library at http://www.ciolek.com/WWWVL-Buddhism.html (26.4.011).
Resources for Indological scholarship can be found at http://indology.info/ (26.04.11).
Another site rather more related to the practise of Buddhism in a Western context is http://www.dharmanet.org/ (26.04.11).
Between them these sites should give you access to all the internet resources you might need.
