| Types of Subdivisions
|There are four main
types of subdivisions:
However, listing all of the subdivisions available for each heading would add several more volumes to the already large LCSH. To solve this problem, there are free-floating subdivisions and pattern headings, both of which are included in the first volume of the LCSH (in newer editions). The free-floating subdivisions are also published separately (call number LC 30.2:F 87 ).
In the 27th ed. of the LCSH, more than 3,300 free-floating subdivisions are listed. These subdivisions can be added to the headings by following the instructions (usage notes) following each entry. For example:
Pattern headings are used to assign free-floating subdivisions to a category of subject headings. For example, in the category of "Educational institutions -- Individual," the pattern heading given is Harvard University. This means that the majority of free-floating subdivisions that can be assigned to a university or college will be found in the entries for Harvard University.
So, if subdivisions are needed for the University of Mississippi, any of the examples under Harvard University could be used.
A copy of the Table of Pattern Headings is given below.
