U.S. officials say the U.S. Naval Academy has removed nearly 400 books from its library after being told by Defense Secretary Pete Hegseth’s office to review and get rid of books that promote diversity, equity and inclusion.

The Prejudicial Materials Working Group (PMWG) of the RBMS Controlled Vocabularies Editorial Group (CVEG) was convened in the summer of 2020 to review, revise, and generate new terminology in the RBMS Controlled Vocabulary for Rare Materials Cataloging (RBMS CVRMC) that would be useful for indexing works that are prejudicial in nature, or that are the byproduct of prejudicial and hateful systems and ideologies. This work included review and revision of scope notes and relationships between terms.
