Sejarah Trier
"There is not much literature in English on Trier. The three volumes on Trier's history published by the history department of the University of Trier between 1985 an 1996 represent a complete history including all researches up to the time when they were published. Clemens' 2007 book (Clemens is a history professor of Trier University, earlier he worked at the Roman Museum in Trier) can be viewed as an update."
