To my knowledge, no one has stepped forward to support a Louisiana regimental history series similar to the volumes published on Virginia units. H. E. Howard at one time was thinking about expanding his series to include other states, but I have not heard anything about those plans in several years.
The Howard Virginia series, for all of its positives, has a number of negatives about it (no index, no notes, etc.). If anyone begins a Louisiana project, I hope they will avoid those problems.
