The #bookstr đ macro is hierarchical. If you find a section or verse event, in the wild, you can just drop the section tags, to find the whole chapter, or the section and chapter tags, to find the whole book. This means you can always backtrack to the entire publication, from just one quoted line or paragraph.
We are going to be having these tags in all of our publications, so you will be able to "Bible-search" and "Bible-cite" any of our books!
I love books. Name checks out. đ
