Very sad news. I wonder how something good can be rescued from this.
I don’t think the BAA could commission something like the Yearbook, but we do already have our Handbook, and maybe that could be expanded, with the cooperation of some of the people who were contributing to the Yearbook, to include some of the most useful material from the Yearbook that it does not already cover. We could make the Handbook more pictorial and diagrammatic, market it more outside the Association, and charge an appropriate price to non-members. Maybe we could also pay something to contributors. However, that would require detailed consideration.
