This bibliography of Ludwig Wittgenstein is limited to the doctoral dissertations submitted in North American Universities. It covers almost all aspects of Wittgenstein's thought. Compared with K.T. Fann's "Wittgenstein Bibliography", published in the International Philosophical Quarterly Vol. 7 1967 pp. 311-339, where there are only seventeen references to Ph.D. dissertations, this present list cites more than one hundred and twenty five. Further, the dissertations which have been published are indicated.

During the 1982 Canadian Philosophical Association Meeting in Ottawa, a workshop on the philosophy of religion in Canada was held. Its participants were all contributors to a previously published book edited for the University of Ottawa Press, entitled Analytical Philosophy of Religion in Canada, who were thus given the opportunity to comment on their own positions and to reply to the criticism that had been made of them.
