I just received my copy of Studien zur römischen Schwertbewaffnung in der Kaiserzeit Vol. 1 and 2 (Studies on the Roman sword under the Empire Vol. 1 and 2). It is a vast pool of information and pictures of Roman swords and accoutrements from the Republic era to the late Empire. It includes some important information about the Gladius Hispaniensis. These books arrived just in time to help inform my current project. The only downside is I do not read German, so it is a lot of translating with Google Translate which creates some interesting sentences in English. 😉
