History of Education Quarterly has published an excellent forum on the history of the U.S. Department of Education. On BlueSky, Jack Schneider of the University of Massachusetts posted non-paywalled links to each of the articles, and hopefully those links will also work here. (If not, these should be available from academic libraries).
The titles themselves reflect the scope – and historic necessity – of the work currently being dismantled.

Early efforts to expand and fund public education in the United States assumed that democracy required an educated populace who could deliberate together about shared public concerns. The Secretary of Education declared this week that children still attending school during the government shut down was proof that the Department of Education wasn't needed. Therein is evidence of the threats that the intentionally uneducated pose for democracy, as the Secretary has no idea why we had DOE (or at least pretends not to) and what we now lose in its destruction.
