Bibliophilia is not to be confused with bibliomania, a potential symptom of obsessive–compulsive disorder involving the collecting of books to the extent that interpersonal relations or health may be negatively affected, and in which the mere fact that a physical object is a book is sufficient for it to be collected or beloved. Some use the term "bibliomania" interchangeably with "bibliophily", and in fact, the Library of Congress does not use the term "bibliophily," but rather refers to its readers as either book collectors or bibliomaniacs.
