The Institute holds two library collections:
1) The Gino Germani collection of social sciences, history and comparative studies (donated to the Center at the time of its founding);
2) the E.A. Bayne collection of Mediterranean Studies and International Relations (subsequently donated to the Center by the American Universities Field Staff).
The unification of two important cross-cultural libraries – which contain numerous classic works in history, sociology, economics, political science, international relations, strategic studies and anthropology – was highly praised by the US Library of Congress in 1984 (see the letter sent by the US Librarian of Congress).
