This book contains studies of seven non-English languages spoken in Texas, Oklahoma and Louisiana, as well as a final chapter based on data obtained from Swedish-English bilinguals in Massachusetts, Illinois, and Minnesota. The individual studies are: Lurline H. Coltharp, "Invitation to the Dance: Spanish in the El Paso Underworld"; Janet B. Sawyer, "Spanish-English Bilingualism in San Antonio, Texas"; Virgil L. Poulter, "A Comparison of Voiceless Stops in the English and Spanish of Bilingual Natives of Fort Worth-Dallas"; Raleigh Morgan, Jr., "Dialect Leveling in Non-English Speech of Southwest Louisiana"; Glenn G. Gilbert, "The Phonology, Morphology, and Lexicon of a German Text from Fredericksburg, Texas"; William Pulte, Jr., "An Analysis of Selected German Dialects of North Texas and Oklahoma"; Joseph B. Wilson, "Unusual German Lexical Items from the Lee-Fayette County Area of Texas"; Reinhold Olesch, "The West Slavic Languages in Texas with Special Regard to Sorbian in Serbin, Lee County"; Jan L. Perkowski, "A Survey of the West Slavic Immigrant Languages in Texas"; Kjell Johansen, "Some Observations on Norwegian in Bosque County, Texas"; Nils Hasselmo, "Code-Switching and Modes of Speaking." The editor feels that the present collection is valuable in demonstrating the great linguistic diversity of an area reputed to speak only Spanish or English. (FWB)
