Free-floating subdivisions are called by this term because they "float freely" from one subject heading to another, without having to be specifically established in each instance. There are several different places where information about these subject subdivisions may be obtained.
The most complete information is available from the Subject cataloging manual : subject headings. This reference tool includes several sections detailing the freefloating subdivisions--a list of the different sections is provided. Where available, the most current information will be found with the Subdivisions Online.

The term "free-floating" is actually used to encompass several different lists of varying usage. These lists include:
The latest versions of these lists are found in the Subject cataloging manual : subject headings, volume two, in sections H1095 through H1145.5. The manual will not only list the subdivisions, but in certain cases may also include notes following the individual subdivisions, with relevant restrictions.
More recently, Form Subdivisions have been marked with a diamond symbol in the margins. See also the Freefloating Form Subdivisions list.
Example
 --Acronyms (H 1206.5) |
sh85-667 |
These notes may include information about sections in the manual that contain more complete information, notes about whether the subject subdivision may be further subdivided by place and references to other subject subdivisions. If this information is already included on an LC subject authority record, the record number is listed.
Example
| --Economic aspects (May Subd Geog) | sh85-40850 |
See also --Economic conditions under names of countries, cities, etc., and under classes of persons and ethnic groups, including occupational groups, for works discussing the economic history or economic conditions in general of a place, class of persons, or ethnic group.

LC may also create a reference record for a subject subdivision.

The subfield SUBJ should also be changed, and coded c, provided the record includes a public note; if not, change the subfield to a. This will allow the note to display to the public. This change does mean that when the Conflict and Error detection program is run to check for problems with the heading use codes that this record will show up as a problem. It will need to be ignored.
If your bibliographic record incorrrectly contains the term given in the Reference record as a heading, CLARR will also produce and error message ! which signals that the heading Matches a see reference or something else improper.

The cataloguing utility program CLARR maintains its own internal list of free-floating subdivisions. When you check a bibliographic record using this utility, it will disect the subject headings, and evaluate the subject subdivisions. It will notify you that the heading matches its list of free-floating headings; however, it does not do an effective check for the restrictions that may exist on the use of the subdivision. If in doubt, check with the Subject cataloging manual : subject headings.

In addition to the chronological subdivisions specifically listed under topics, there are certain freefloating time subdivisions as well. These are as follows:
In addition, under names of places, you may also use the century subdivisions after the following subdivisions:
