That’s a really good question. At least in my mind, most of the BOC stuff has been for organizations, like nonprofits, and lawyers looking to study into the field.
Van Lindberg’s book Intellectual Property and Open Source was written specifically for a coder audience. It’s a little out of date, but still worth the read. Especially if you can find a cheap used copy.
For history and broader context, I’m a big fan of Kelty’s Two Bits, which is available free online. Especially Part II of the book. Skip the big academic part at the front situating in the literature, which runs about 100 pages. As Chris told me, “the first 100 pages got me tenure, whereas the middle and last part of the book are the heart of the research and the story”.
Kelty’s most valuable if you’re already familiar with some of the propaganda/philosophy for mass hacker consumption circa 2000. The FSF “philosophy” pages. Eric Raymond’s writings. That sort of thing.
I’ve also done some standalone writing for general and technical audiences:

I probably recommend Heather Meeker’s books more than any others. But those are books by a technical person written for businesspeople. The first chapter of her latest is actually a “just enough software” chapter for non-technies stepping into the subject.
