@Constantius: yes, that's the one. it's about 10e so, quite cheap. ok, i'll probably buy it.
btw, SBH you think Jones' work is better than Bury's as far as i understood? you probably think of:
A.H.M. Jones- ‘The Later Roman Empire 284-602: A Social, Economic and Administrative Survey’
do you mind specifying where exactly Bury's work is outdated? cause i'm not interested in every single aspect of the Empire, I'm mostly into Administrative/Military system.
