Lamination is construction by an over layering facet, just as one makes a sandwich by layering a vegetable over a layer of bread. According. to Ranganathan "when the basic layer is a basic subject and the other layers are isolate ideas, a compound subject is formed". Lamination is of two types:

Lamination 1: In this mode, one or more isolate facets are laminated over a basic facet. This results in compound subjects.

Examples: 1) Anatomy of the human body Basic facet Medicine

Isolate facets = Human body, Anatomy

2) Treatment of diseases of plant

Basic facets = Botany

Isolate facets = Plants , Diseases, Treatment

Plants, Diseases, Treatment (P) (MP) (E)

Lamination: In this mode two or more sub-facets of a compound facet are laminated over one another. Such subjects were called earlier as non-main basic subjects, the components of which were host main subject. The latter had the canonical/special/ environment/system component.

For example, the ayurvedic system of medicine is a non-main basic subjects. In this example medicine is the host-main subject and the ayurvedic system is the system component.
