It has taken a day and a half, and I have foregone sleep, but there is far more information readied for the Blue Peter Book posts. I have also scheduled a post (on indexes others are writing) for Substack later.
The plan was that I would churn out digest histories for the rest of the year, but there is a great deal which others have overlooked which needs some attention.
Some of the resources I am using might get uploaded as general reference material for others to make use of as well.
