The Library of Congress Subject Headings are an integral part of bibliographic control, which is the function by which libraries collect, organize and disseminate documents. The Library of Congress Subject Headings are applied to every item within a library’s collection, and facilitate a user’s access to items in the catalogue that pertain to similar subject matter. The controversy surrounding the subject heading “illegal alien” is that “alien” and “illegal alien” are pejorative terms. Republicans like Ted Cruz of Texas, Jeff Sessions of Alabama, said there is no other way to put it, the library has bowed to the political pressure of the moment. They believe that term “illegal alien” is a factual term and if it is changed then it means the Library of Congress won’t be serving all factual information. Melissa Padilla was doing research on immigration at the library of Dartmouth College and came across that term. She entered a petition to remove that term from its subject heading. Joaquin Castro, Democrat of Texas, agrees with her. My thoughts on thoughts on the government overruling subject-heading decisions made by the Library of Congress through legislation is that it was the right thing to do. My views on the matter is a little bias because both my parents are from South America and the term “illegal aliens” is very derogative.
