High Quality Content by WIKIPEDIA articles! Papers from the Institute of Archaeology, or PIA, is a peer-reviewed academic journal, published annually by the Institute of Archaeology at University College London (UCL). The journal was established in 1989 by postgraduate researchers from the Institute—the largest archaeological department in the UK and one of the largest in the world—with its inaugural issue published the following year. PIA 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 in International Bibliography of the Social Sciences.
