This volume investigates the linguistic and literary evolution of the English language during the Early Middle English period. J. A. W. Bennett, a noted scholar of medieval literature, compiles a comprehensive selection of texts to illustrate the transition from Old English to the recognizable forms of Middle English. The work provides a structured framework for students and researchers to analyze the syntax, vocabulary, and stylistic shifts inherent in the period's verse and prose.

Scholars and students of medieval philology frequently cite this text as a foundational resource for navigating the complexities of pre-Chaucerian English. The inclusion of the glossary by N. Davis is widely regarded as an essential tool for those engaging with the linguistic nuances of the period's primary sources.
