Some of the books I’ve found so far, but nothing much on Beowulf (2007, 1999)…
The Medieval Hero on Screen: Representations from Beowulf to Buffy by Martha W. Driver, Sid Rayand Jonathan Rosenbaum (1 Jul 2004)
some references and sources for FEMALE AUTHORITY in Anglo-Saxon (Beowulf) context or early Medieval. Not much seems to appear around, this is just a google scholar search that I will need to redefine more.
