Bibliographic Control in Theory

The term &dquo;bibliographic control&dquo; presents certain difficulties, not only in translation to other languages but also in English. In the first place, &dquo;bibliographic&dquo; carries the connotation of &dquo;book&dquo; information in printed form, although the types of materials being acquired by libraries and being used by their clientele are no longer limited to books. In fact, some specialists in the organization of all types of materials have coined new terms to express the process of listing them: &dquo;mediagraphics&dquo; seems to be the most general, but words such as &dquo;discography&dquo; have also entered the language to describe particular efforts to identify a specific medium other than the book.
