At Lauds (morning office), we pray Psalm 67. But BDP would have you begin Lauds and then either recite Psalm 67 from memory (every good Benedictine should be able to do this!) or flip to P. 909 which is what I would have to do because I have not memorized this Psalm.
This red-bordered Lauds tabbie marks the first group of dividers I keep together and move
day by day in the Ordinary/Weekly Psalter pages 935 - 1141 which is the main
part of the book and the place to begin most offices.
