The National Geographic television channel has been running a 7-part documentary series on animal migration entitled Great Migrations. It covers a wide range of animals, e.g., birds of various kinds, red crabs, monarch butterflies, and sperm whales.
At 070.1 Documentary media, educational media, news media is the class-elsewhere note: “Class documentary, educational, news works themselves and discussion of them with the kind of general work or the subject, e.g., general periodicals 050, recorded television programs on investing 332.6.” Since class-elsewhere notes have hierarchical force—and as the second example indicates—that note applies to 070.195 Television. The National Geographic television series will be classed with its subject, animal migration.
Browsing the Relative Index for “animal migration” yields the unsubdivided entry:
Animal migration 591.568
Similarly, browsing the Relative Index for “migration” yields:
Migration (Animals) 591.568
The schedule entry 591.568 Migration has in its upward hierarchy:
590 Animals (Zoology)
591 Specific topics in natural history of animals
591.5 Behavior
591.56 Behavior relating to life cycle
The interdisciplinary number—and the zoology number—for animal migration is 591.568 Migration. Examples of works classed in 591.568 are the videorecording of the documentary television series and the companion book: Great Migrations and Great Migrations: Official Companion to the National Geographic Channel Global Television Event. Another example is Animal Migration: Remarkable Journeys in the Wild.
At 591 Specific topics in natural history of animals is the class-elsewhere note: “Class a specific topic in natural history of animals with respect to a specific taxonomic group of animals with the group of animals, plus notation 1 from table under 592–599, e.g., beneficial mammals 599.163.” Since class-elsewhere notes have hierarchical force, a work about migration of a specific taxonomic group of animals is classed with the group of animals.
A work about migration of various kinds of birds is classed in 598.1568 Migration of birds. The number is built with 598 Aves (Birds) plus 1 General topics of natural history of animals from the add table under 592–599 Specific taxonomic groups of animals, following the footnote add instruction at 598 and the add instruction at 592–599, plus 568 from 591.568 Migration, following the add instruction under 1 General topics of natural history of animals in the add table under 592–599. Examples of works classed in 598.1568 are Winged Migration, How Birds Migrate, and The Atlas of Bird Migration: Tracing the Great Journeys of the World’sBirds.
A work about migration of the red crab is classed in 595.386 Brachyura (Crabs). Because the red crab does not approximate the whole of 595.386, no addition is possible. An example of a work classed in 595.386 is Di qiu jia zu: hong xie de qian yi = The Global Family: The Migration of the Red Crab.
A work about migration of the monarch butterfly is classed in 595.789 Papilionoidea (Butterflies). Because the monarch butterfly does not approximate the whole of 595.789, no addition is possible. An example of a work classed in 595.789 is Flight of the Butterflies, which has the LCSH “Monarch butterfly—Migration—Juvenile literature.” (For a children’s book, many libraries will prefer the shorter number given in the abridged edition: 595.78 Moths and butterflies.)
A work about migration of the sperm whale is classed in 599.5471568 Migration of Physeteridae (built with 599.547 Physeteridae plus 1 General topics of natural history of animals from the add table under 592–599 Specific taxonomic groups of animals, following the footnote add instruction at 599.547 and the add instruction at 592–599, plus 568 from 591.568 Migration, following the add instruction under 1 General topics of natural history of animals in the add table under 592–599). At 599.547 Physeteridae is the class-here note “Class here Physeter (sperm whale)”; that note indicates that the sperm whale approximates the whole of 599.547 and thus that addition is possible. An example of a work classed in 599.5471568 is Whales, which has the LCSH “Sperm whale—Migration—Juvenile literature.” (For a children’s book, many libraries will prefer the abridged number: 599.5 Cetaceans and sea cows.)
