Notes on the List

Liber I originally was a Class B document, but was changed to Class A in 1913.

Liber LXI was originally Class A, then changed to Class B, then changed to Class D.

Liber CCXX and Liber XXXI are essentially the same. The latter is the handwritten original. The reason for the two documents comes from Liber Al: III, 74, which states Paste the sheets from left to right and from top to bottom: then behold!

Liber CCCCXVIII has instructions in Aethyr 8 and 18 which are to be regarded as Class D. As it is a diary, it more properly belongs in Class B, except for the parts that the Angels dictated. Parts which are not consistently and clearly demarcated.

Liber DCXV, more commonly known as The Paris Working is a magickal diary. The Class A material is so intertwined that segregating them apart is extremely difficult.

Liber DCCCCLXIII is Class A for the introduction only. The rest of the text is Class B.

The Stèlle of Revealing is not part of the Holy Books, despite it being a part of the Gnostic Mass (Liber XV) that is performed by Thelemites as part of their sacred rituals.
