Roger Shuy and Ralph Fasold's introduction describing sociolinguistics as (1) a desire to refine linguistic theory, (2) an attempt to describe the sociocultural matrices of language, and (3) an effort to apply sociolinguistic knowledge to this monograph. Walt Wolfram contributes substantially to the development of sociolinguistics theory in "Overlapping Influence and Linguistic Assimilation in Second Generation Puerto Rican English"; David Smith, in "Some Implications for the Social Status of Pidgin Languages," spells out some of the linguistic features concomitant with a particular sociocultural context; David Minderhout applies a framework already developed and tested for sociocultural analysis in "The Entrepreneur's Use of Language"; Roger Shuy discusses the Norfolk Project in"Sociolinguistics and Teacher Attitudes in a Southern School System"; and Mobolaji Adekunle outlines some sociolinguistic facts which should be taken into account in making decisions involving language policies in "Sociolinguistic Problems in English Language Instruction in Nigeria." Dell Hymes, Alfred Opubor, and A. B. Hudson conclude the monograph by offering comments on the various papers. (HS)
