"[<em>The Black Books</em>] represent the coalface of Jung’s introspection, from which he mined and polished his more accessible <em>Red Book</em>.… <em>The Black Books</em> details Jung’s visionary encounters with entities such as Phanes the star god, Ha the sorcerer, and Philemon, the wise magician who became Jung’s internal guru."

- Phil Baker - Times Literary Supplement,

"The hundreds of thousands who have bought the <em>Red Book</em> and have profited from studying it will in all probability also read the <em>Black Books</em> and this will add to the urgency in the professional analytic world for analysts to integrate an understanding of these primary sources for interpreting and teaching Jung’s legacy... This first edition of the <em>Black Books</em> in seven separate volumes has been prepared with exemplary care. The first volume is a stand-alone Introduction which will repay careful reading and re-reading for contextual guidance through the six notebooks. Each of these is presented in facsimile form followed by English translation, providing as close an experience as is possible to handling the original books, right down to front and back end papers which replicate the originals. High quality paper, smart red silk headbands and a substantial slip-case give this the aesthetics of a luxury edition to complement the exemplary style of the facsimile <em>Red Book</em> edition."
