More active research is going on at http://www.qbwiki.com/wiki/Battle_of_the_Brains (it looks like this page was mostly copied from there). That page always uses "Maggie Walker" to refer to the "Governor's School" for clarity, as it is aimed at a national audience that may not be concerned with when specific schools in Richmond changed their names. It also has more info on Battle of the Brains prior to 1985.
