Papers from the Institute of Archaeology (PIA) is an annual peer-reviewed academic journal published by Ubiquity Press on behalf of the UCL Institute of Archaeology. The journal was established in 1990 by postgraduate researchers from the Institute. The journal was initially conceived as a venue for publishing research papers produced by UCL archaeology postgrads and staff on new findings and novel approaches to archaeological theory. It later expanded its contributor base to postgrad researchers from other UK institutions and abroad. It is abstracted and indexed in the International Bibliography of the Social Sciences and ArchLib, and is a member of the Committee on Publication Ethics.
