TUCSON, Ariz. (AP) _ Nahum N. Glatzer, a scholar, editor and author of numerous works on literature and Judaism, has died at 86.

The Watertown, Mass., resident, who wrote more than 250 books and articles on subjects ranging from Franz Kafka to Jewish prayer, died Tuesday after several days in a coma in Tucson, where he was spending the winter.

A founder of Schocken Books in Germany, he remained an editor after the publishing company moved to the United States during the Nazi era.

Glatzer was born in Austria and in 1931 earned a Ph.D. from the University of Frankfurt, where he was philosopher Martin Buber's successor as lecturer on Jewish religious history and ethics.

In 1933, Glatzer and his wife fled to Palestine, where he taught literature. They moved to the United States in 1938.

Glatzer began teaching at Brandeis University in Waltham, Mass., in 1950 and was chairman of the department of Near Eastern and Judaic studies for 11 years. He later became a professor of religion at Boston University.

Among his works are ''History of the Talmudic Age,'' ''The Beginnings of Post-Biblical Judaism'' and ''The Dimensions of Job.''

He is survived by his wife, Anne; a son; a daughter, and two grandchildren.

Funeral services were set for today in Lexington, Mass.
