Keiko Okuizumi completed her memoir earlier this year, in which she describes her late husband Eizaburo's work as a librarian at U.S. universities who had a special interest in censored publications in occupied Japan after the end of World War II.

Eizaburo's major work consisted of sorting and filing thousands of Japanese books, booklets and magazines collected by an American scholar who had worked at the censor office of the Allied Forces' General Headquarters.

Keiko said he was "firmly committed to the work," which many in the field of Japanese studies have come to appreciate for showing the reality of life in Japan just after the war.
