It is an important reference work for all scholars of Roman Britain.
This monumental work was initiated by Francis J. Haverfield, whose notebooks were bequeathed to the University of Oxford.
Volume II contains, broadly speaking, the inscriptions found on instrumentum domesticum (Latin for 'domestic utensils').
There are also indexes published to the volumes allowing the scholar quickly to reference nomina and cognomina, military units, imperial titles, emperors and consuls, deities and so forth.
Entries are also cross-referenced to the CIL and other indexes and journals as necessary.
