Since Reading Lists are public, sometimes users want to have a private Reading List functionality (see e.g. this recent thread). Personal books are well suited for that - after all, they allow inclusion of Logos resources owned and not owned (and titles of non-Logos resources), links etc. PBs even allow input fields to not only tick off, but capture ideas and relevant learnings. As a proof of concept I share a PB source that gives a Reading List for the Great Commission (based on the RL by MJ.Smith).

You may want to compile the PB as type lectionary instead of monograph, if you wish to utilize the bible version picker for dynamic text of the Key Passage.
