Book excerpt: The continuing expansion of research in dialectology, sociolinguistics and English as a world language has made the field increasingly difficult to survey. This bibliography is intended to provide a comprehensive overview of the relevant publications of the past few years. Like its predecessor, it will prove an indispensable reference book. The collection is in four parts, dealing respectively with general studies, Britain and Ireland, the United States and Canada, and the rest of the world. There is a joint index in which the 2800 entries are classified according to specific areas, ethnic groups and major linguistic categories, thus making the bibliography easy to use with the greatest profit. The present bibliography complements the one compiled by W. Viereck, E.W. Schneider and M. Görlach, which covered the period from 1965 to 1983 and was published in the same series in 1984.
