First published in 1980, Language and Social Networks has had a great influence on the development of sociolinguistics. The second edition incorporates an extensive new chapter reappraising the original research and discussing other sociolinguistic work in the same paradigm.
since I developed an interest in social network analysis, I have been reading some of the coolest linguistics ever. This seminal work was already so cool, and from what I know of more recent research the field just keeps getting cooler and cooler. I just love sociolinguistics
