In the light of the previous discussions re. rubrics and hyper-ritualizing, I am a bit surprised to find extremely detailed instructions in the How to Use section of The Treasury of Daily Prayer.
"The ribbons are used, in the order and for the purposes as indicated in the list that follows. If you use this order, you are less likely to tangle the ribbons as you use the Treasury."
"Dark Green = marks the Church Year calendar section."
"Gold = marks the current day in the Church Year."
"Red = marks the order of prayer you are using (all orders are in the center of the book)."
"Purple = marks the additional prayers you may choose to use daily."
"Light Green = marks your place in the Psalms."
"Blue = marks "Prayers for the Baptized Life" or any place in the book of your choice."
There follows, then, "detailed, step-by-step" instructions on how to correctly insert the ribbons into the book, how to use them to (correctly) mark the appropriate sections of the book, and how to manipulate them during the recitation of the office.
What I found most amusing about this set of instructions is this statement: "If you use this order, you are less likely to tangle the ribbons...." This, I think, is the ultimate of hyper-ritualizing.
