Mike Olson writes: “Library catalogs have always been battlegrounds where content is not merely described but debated. President Trump’s Executive Order 14172 directing the renaming of longstanding geographical designations ‘Mount Denali’ and ‘Gulf of Mexico’ to the politically loaded ‘Mount McKinley’ and ‘Gulf of America’ reveal the naked truth of what cataloging has always been: a battlefield where meaning is contested and conquered. When catalogers implement politically motivated terminology changes, they become unwilling performers in a linguistic ritual that normalizes certain worldviews while erasing others. But there’s potential for subversion within these systems.”
