I am in the process of both deepening my practice and beginning to
study the Pali Canon as an academic. My question regards the latter.
Does anyone have any recommendations for scholarly books and/or
articles that trace the historical development of the Theravada Canon,
i.e., older sections, newer sections, and so on? Also, I still need to
get a firm grasp on the historical development of the different Nikaya
schools in India and their respective doctrinal positions. I'm
currently reading Hirakawa/Paul Groner's _History of Indian Buddhism_,
but it's not quite as in-depth as I had hoped and it's probably also a
bit dated.
