Collins is a bit of a guru on Spain. I only picked this up recently but I’m really enjoying it.
Coulston, J. C. N. (1990). Later Roman armour, 3rd-6th centuries AD. Journal of Roman Military Equipment Studies, 1, 139-160.
Presents a good argument for mail armour, and against leather armour, in the late Roman army. Unfortunately my own Legionaries have leather armour.
Graves, R. (1938). Count Belisarius. Penguin.
Quite a good novel. Overdoes the evil Justinian thing, but still worth a read.
Heath, I. (1980). Armies of the Dark Ages 600-1066 (2nd ed.). Wargames Research Group.
Excellent.
MacDowall,S. (1990). Goths, Huns and Romans. Argus Books.
This small booklet is pitched at the wargaming community. It provides a good introduction to the history and to wargaming the period. Includes sample scenarios.

I only used this for the list of Visigothic Kings.
