If you're a Romanist, you'll know about TRAC - the Theoretical Roman Archaeology Conference. It's the archaeology that's theoretical, not the conference ... anyway, the first TRAC conference was held to widen the range of perspectives offered, and voices heard, in Roman archaeology. This was a major success, and TRAC has made a major contribution to research in Roman archaeology over the past 25+ years.
Now TRAC announces the launch of a fully open-access online journal, the Theoretical Roman Archaeology Journal (TRAJ) published and supported by the Open Library of Humanities (OLH) - here. Articles are available now, free of charge of course, and include Michael Fulford: Silchester: The Town Life Project 1997–2014: Reflections on a Long Term Research Excavation, Nico Roymans and Manuel Fernández-Götz: Caesar in Gaul: New Perspectives on the Archaeology of Mass Violence, among others.
The launch reflects a growing tendency towards open-access publishing in the humanities.
