'PIE-Peter Lang evolved from the takeover by the Peter Lang Publishing Group of Presses Interuniversitaires Européennes (PIE), a Belgian publishing house founded in 1985.'
'Their list, which originally concentrated on the history of European integration, has been expanded to cover all areas of the humanities and social sciences. Most of their titles are published in series that treat such diverse topics as European history, politics, environmental studies, drama etc.' (Source: Publisher's website)
