Just two pieces of Bourdieu on methodology that I found useful:
Bourdieu, P., & Zanotti-Karp, A. (1968). Structuralism and theory of sociological knowledge. Social Research, 35(4), 681-706.
Bourdieu, P., & Wacquant, L. J. D. (1992). An invitation to reflexive sociology. Chicago, IL: Chicago University Press.
Feel free to add if you know more! And if you want the PDFs just drop me an email: thomas.cyron@ju.se
