Here is a brief selection from the text that might help in separating the difference between what constitutes "the rites of the Necronomicon" as distinct from "rites based on the Necronomicon."
"Necronomicon" here refers to the common paperback "Simon" text, which was for many people (including myself) the first complete occult text available for their inspection. It's cheap, common, well-written, and fascinating. Hopefully this will stimulate discussion on the book and the rites it prescribes.
This is typed from a very brief re-reading of the text, so I may have missed something, but nothing has been added from outside the text. I've omitted the entire Maqlu text, since those spells are supposedly used after something has gone wrong, and the entire Urillia (R'lyeh?) text since those rites are for the "bad guys." What follows is a summary of what you are told to do in order to call spirits according to the Necronomicon.
All seals are supposed to be made while alone, kept in silk colored as shown, and taken out only when the planet is visible. I might be wrong, but I think the "Gates of the Necronomicon" book details the appropriate times in a more user-friendly format, but I haven't read it and am not certain.

I don't know if there are specific forms used to conjure the spirits given in the book. Maybe I missed them, but such is the part of the process that is clear.
This is my condensed version from the book.
