Suggestion

Victor—you've taken on a complicated and hard-to-distill topic, and I'd say you've been successful with the sections you have up so far. They're clear, to the point, and very informative!

One suggestion to sneak into the introduction (or wherever you see fit): I think the 'passive custodian' vs. 'active archivist' conversation is an interesting and relevant one to include. I think a outlining how that idea and discussion has evolved over the last 50/40ish years would give your page a boost in context. Maybe the lay-person thinks archivists are old stodges who read books in dusty basements—how did the profession come to understand itself as playing an important role in public advocacy?
