KENNICOTT'S CRITICAL EDDITION OF THE MASORETIC TEXT
Benjamin Kennicott produced the first critical edition of the Masoretic Text, with variants from 615 Hebrew manuscripts and 52 early printed editions.
This book (Volume 2) also contains Kennicott's "General Dissertation on the Hebrew Old Testament with Various Readings, from Manuscript and Printed Codices" in which he details his perspective on the history of the Hebrew Bible. (Note: The Dissertation is in Latin.)
Because Kennicott's critical edition contains a magnitude of information, collated from hundreds of Hebrew manuscripts, it is a valuable resource for anyone interested in the study of the Masoretic text. It also bears witness to the incredible care and precision by which the Masoretic preserved the Hebrew text of the Bible.
Volume II: Isaiah - Second Chronicles.
