The book is an excerpt from the Advanced Book of Freemasonry. It does have the degree work for memorization but does not include the diagrams for placement of the participents in the degree itself like the books from the York Rite Bodies. The great part is the parts in a larger format for easier reading. The excerpt is as it says and does not include the two prior degrees before the final degree of Knights Templar. There are blank pages at the end for notes and diagrams if one chooses. I honestly have not compared the ritual itself to the current ritual from the Grand Encampment. The ritual is close as I remember from going through the degree.
