This volume contains a collection of articles that present studies of medieval Karaite texts. In recent years many new medieval manuscript sources of Karaite texts have become available that show the central role that the Karaites played in the development of medieval Jewish thought. The articles in the volume concern primary manuscript sources, the majority of which have not been published so far. They examine various topics in Biblical exegesis and grammar. Exegesis and grammatical thought were intimately connected in medieval Karaite scholarship. This voliume reflects this close relationship between the two disciplines. It also shows the diversity of thought on medieval Karaism, which was a feature that gave it such vitality and creativity.
