b'Maintaining a Catalog / Making ReferencesThe following are some types of unpreferred terms that might be used as See references in a catalog:1) Synonyms or terms so nearly synonymous that they would cover the same material. For ex-ample, Instructional materials centers requires a reference from School media centers.2) The second part of compound headings. For example, Antique and vintage motorcycles re-quires a reference from Vintage motorcycles.3) The inverted form of a heading, either an adjective-noun combination or a phrase heading,especially if the word brought forward is not also the broader term.For example, Theory of knowledge requires a reference from Knowledge, Theory of, there beingno heading Knowledge.4) Variant spellings. For example, Archeology requires a reference from Archaeology.5) The opposite of a term, when it is included in the meaning of a term without being specifi-cally mentioned. For example, School attendance requires a reference from Absence fromschool and from Absenteeism (Schools), and Equality requires a reference from Inequality.6) The former forms of headings revised to reflect common usage, when the older term still hasany currency. For example, Negroes remains as a reference to Blacks and to African Ameri-cans, but Dinosauria is no longer retained as a reference to Dinosaurs.The first time a heading from the List is assigned to a work in the collection, the terms in the UFfield in the List are entered, at the catalogers discretion, as See references in the public catalog.When the same heading is subsequently assigned to other works, the references are already in place.When the cataloger adds a heading to the authority file as needed, all the appropriate See referencesare entered as well the first time the heading is used. For the heading College studentsAlcoholuse, for example, suitable See references might be Campus drinking, College drinking, andDrinking on campus.See also ReferencesIn the public catalog See also references direct the user from one established heading to anotherestablished heading. Under most headings in the Sears List, following the BT [Broader term] label,is a term that is broader in scope than the heading itself. As a rule, a term has only one broader term,unless it is an example or aspect of two or more things. The broader term serves two functions in theList. The first is to aid the cataloger in finding the best term to assign to a work. If the first term thecataloger thinks of to describe the contents of the work does not cover all aspects of work, thebroader term may be the more appropriate heading for that work. The second function is to indicatewhere See also references should be made in the public catalog. A See also reference is made from abroader term to a narrower term, but not from a narrower term to a broader term. Take, for example,the broader term Clothing and dress on the heading Gloves. When the heading Gloves is assignedA-46'
