This 6″x 8″ Apollo 15 CSM Updates training manual dated March 29, 1971 was used in the Mission Simulator and then used for study in the astronaut crew quarters just prior to mission launch.
The checklist consists of six tabbed sections including P30 Maneuver, P37 Block Data, Earth Orbit Block Data, P27 Update, P24 Landmark Tracking and Flight Plan Update.
Particularly enjoy the annotations (most likely made by CMP Al Worden) that have been made in various parts of the manual.
