Literature about Marian Reforms

[Lysandros]

Hallo everyone,
as I know there are others on the forum who are into ancient history also on an academic level, I thought I could ask here if anyone can recommend literature about the Marian Reforms. I am writing a paper about it and I had difficulties in finding preferably up-to-date literature on the topic. What I have found and read so far is:

More important:
Emilio Gabba: Republican Rome, the Army and the Allies (Translated by P. J. Cuff), Oxford 1976.
Peter A. Brunt: Italian Manpower 225 B. C. – A. D. 14, Oxford 1971.

Less important:
Lukas de Blois: The Roman army and politics in the first century before Christ, Amsterdam 1987.
Thomas F. Carney: A biography of C. Marius, Chicago 1970.
Volker Werner: Quantum bello optimus, tantum pace pessimus: Studien zum Mariusbild in der antiken Geschichtsschreibung, Bonn 1995.

Any help is gladly appreciated!
