This six volume limited facsimile edition contains Scholem's observations and at the end of each volume, follow notes which were found in the books, on loose slips of paper. Scholem deals with expressions which are singular to the Zohar. He points to their origin in the Midrashim or in medieval literature or in foreign languages. Scholem's comments are not confined to pointing our parallels. Sometimes Scholem himself interprets a statement of the Zohar, occasionally he continues the logic of the Zohar, deriving from it theological conclusions. Other times he relies in the work of others, referring to the scholarly literature.
