Comparability in Social Research [PDF ebook] 

Originally published in 1969, Comparability in Social Research is a collection of essays from the British Sociological Association and Social Science Research Council. The essays are the result of a working group from the British Sociological Association, and a response to the need for the development of sociological theory as a scientific discipline. The essays examine the comparability of data assembled by research, in several sociological fields. This edited collection includes essays on the topic of education, family and household, income and occupation.
