Again citing Art Bergeron,
When the Louisiana state legislature commissioned this work, it was intended to include brief histories of all military commands. Booth's publication contains only an indiscriminate alphabetical list of companies. Booth then took all state rolls available and printed names in alphabetical order, regardless of whether or not a man belonged to a Confederate unit or the militia.
Booth's title and his inclusion of militia records is an oversight. It's like confusing a boat with a ship, or calling a rifle a "gun". Reasonable people do it every day.
Having long considered publishing a book on Alabama Confederate unit histories, I could've been guilty of exactly the same thing. The outline had always included a section on Alabama militia commands. However, my title would have suggested that militia were counted among Confederate military units. I can either change my proposed titlle or put the militia in a separate volume.
I don't wish to make the same mistake as Booth made. Thanks for calling this to my attention.
