Progress report

I finished & checked the layouts for Parts 3 & 4 (which together are about equal in length to Part 1 or Part 2), plus I laid out the front matter and the Resources page in the back. The other bit of back matter is going to be the Index, which…pray for me. I’m going to try giving the layout a final read while indexing it—we’ll see how that goes. This is my first index!
