Consequently we perceive an avalanche of codes each of which is a recognised form of cipher, each capable of attracting the attention of someone with a special knowledge of that particular type of code. I suggest he did this because he wasn't sure if anyone would even suspect the existence of coded information, or to put it another way, he wanted to attract the attention of anyone with a good knowledge of codes. He could have stated that there was coded information within his books, but if it was too simple, that might have resulted in someone deciphering the information before he had sold his secret.
Unfortunately I haven't made any progress in deciphering it other than that which I have decribed on the web site. From the evidence I have described, the existence of the code is undeniable.
