Translated into English, and with some notes, the hymns make two
quite substantial volumes.2 In the original there are some 20,000 metrical verses in the whole collection.
The secondary literature on Kurzweil, including The Baruch Kurzweil
Volume, a series of memorial essays, is
quite massive, while that on Leibowitz — including The Yeshayahu Leibowitz
Volume, a festschrift, and Negation for Negation's Sake, an anti-festschrift — is also
substantial.
