"Arming the Suckers, 1861-1865: Compilation of Illinois Civil War Weapons" is an excellent book for an arms researcher to have in his library.
As for "pushing back" regarding ACW lectures, with arms, in the schools, there is no pushing back in my state, It is not a matter of policy, it flat out against the Laws of the State. That's a legal battle you will not win today.
