Exhibition: Children's Books in the Occupation Period from the Gordon W. Prange Collection, University of Maryland Libraries

The Prange Collection includes many children's books (the book collection including children's books has not been microfilmed yet). From February 1 to April 13, 2003, an exhibition "Children's Books in the Occupation Period from the Gordon W.

Exhibitions followed in Hiroshima, Hokkaido, Kumamoto, Okinawa and Tokyo (ILCL) again. Each exhibition was featured in different ways to highlight each city.

On the opening day of the ILCL exhibition, Dr. Charles Lowry, Dean of Libraries, University of Maryland, and Prof. Shin Torigoe, Graduate School of Seiwa College, gave commemorative speeches. In total, about 22,660 visitors visited the exhibition.
