This short volume provides a comprehensive and synoptic view of Joshua A. Fishman's contributions to international sociolinguistics from 1949 to the present. Readers will find in this volume the essential understandings of Fishmanian sociolinguistics in two short essays that integrate his life's work. The first essay by García and Schiffman identifies the major theoretical contributions and the development of Fishmanian sociolinguistics, often echoing Fishman's own words. The essay by Peltz then analyzes Fishman´s contributions to Yiddish scholarship, as well as the role of that scholarship in his general work. These essential understandings are then extended through Fishman's own concluding sentiments, as well as by the comprehensive and up-to-date bibliography of over 1,000 titles of Joshua A. Fishman's work, compiled by his wife, Gella Schweid Fishman. Together, the contributions in this volume pay tribute to the life work of one of the world's most prolific and original scholars in the field of sociolinguistics -- the founder of what we refer to in this volume as Fishmanian sociolinguistics.
