b'Specific and Direct EntryThe principle of direct entry holds that a subject heading should stand as a separate term rather thanas a subdivision under a broader heading. If the reader wants information about owls, the directapproach is to consult the catalog under the heading Owls, not under the broader subject Birdssubdivided by the narrower topic Owls. In other words, the cataloger has entered the book directlyunder Owls, not indirectly under BirdsOwls, or under BirdsBirds of preyOwls. Thelatter two subject strings are both specific, but they are not direct.A-22'
