In
Changing the Immutable: How Orthodox Judaism Rewrites Its History (The Littman Library of Jewish Civilization, 2015),
Marc B. Shapiro, the Weinberg Chair of Judaic Studies at the University of Scranton, explores how segments of the Orthodox Jewish world rewrite the past by editing or erasing that which does not fit in with their contemporary world-view. He surveys a variety of types of censorship, including the censoring of Jewish thought,
Halakhah (Jewish law), and sexual matter. The book asks us to reconsider the value of the concept of "truth" in Orthodox Judaism.
