6. The full contents of the book are restricted to Level 5 personnel under Order O5-4000-F26. However, official statements have noted that certain rituals and locations described in the book bear strong similarities to SCP-1660 and SCP-860. Recent declassifications have revealed that another passage may have been written in reference to SCP-3560, which was discovered more than 50 years after the book's recovery. The significance of SCP-3560 potentially predating the existence of Anderson Robotics has yet to be determined.
