Step 1: Understand Ranganathan's Three Planes of Work.S.R. Ranganathan proposed that classification work occurs in three distinct planes:\[\begin{array}{rl} \bullet & \text{Idea Plane: Conceptual analysis of the subject.} \\ \bullet & \text{Verbal Plane: Expressing the ideas using terminology.} \\ \bullet & \text{Notational Plane: Representing the terms using a system of symbols or notation.} \\ \end{array}\]
Step 2: Identify the Canons of the Verbal Plane.The Verbal Plane Canons guide the selection and formulation of terms. Key canons include: Currency (use current terminology), Context (terms must be contextually appropriate), Enumeration (systematically list terms), and Reticence (use neutral, non-judgmental terms).
Step 3: Identify the Canon of Array.The Canon of Array, part of the Notational Plane, dictates that notation should reflect the relationships between classes in an array (a set of coordinate classes). This canon concerns the notation's structure, not the terms themselves.
