The Correct answer is A - IV, B - III, C - I, D - II

Key PointsCanons for Terminology:

• Ranganathan introduced several canons for coining and displaying terminology in library classification systems to ensure clarity and consistency.
• These canons aim to reduce the number of terms and promote international understanding.
• Canon of Context:
  • Terms in classification schedules should be read and understood in the context of the broader category.
  • For example, instead of listing terms like "Single salts" and "Double salts," they should be displayed under the general category of "Salts" to avoid repetition and maintain clarity.
• Canon of Enumeration:
  • The Canon of Enumeration addresses the variability of terms and disciplines, advocating for explicit delineation of scope by enumerating subdivisions.
  • This pragmatic approach ensures clarity and consistency in defining subject areas, often achieved through notes in classification schemes like the Dewey Decimal Classification (DDC).
  • Additionally, manuals such as those issued by the Forest Press aid in interpreting class scope uniformly across libraries, promoting standardization and coherence.
  • Canon of Enumeration suggests that terms should denote concepts in a structured manner.
• Canon of Currency:
  • Terminology must evolve with time, as terms can become outdated or new terms may be introduced.
  • For instance, "Library Science" has evolved into "Library and Information Science."
  • Classification systems should update terms to reflect current knowledge and terminology.
  • Canon of Currency ensures that terms are based on the latest developments.
•  Canon of Reticence:
  • Terms used in classification systems should be neutral and non-judgmental.
  • For example, terms like "Negroes" should be updated to "African Americans" to avoid any discriminatory or outdated language.
  • Canon of Reticence avoids unnecessary or excessive use of terminology.
• ​Canon of Simplicity:
  • The Canon of Simplicity in Ranganathan's terminology principles emphasizes that terms in a classification system should be as simple and concise as possible.
  • The goal is to avoid unnecessary complexity and ensure that the terminology is easy to understand and apply.
  • Canon of Simplicity emphasizes that notations should be simple and clear.
• ​ Canon of Consistency:
  • Consistency in terminology usage is essential.
  • Terms should be used uniformly throughout a system, regardless of varying usage or literary preferences.
  • For example, the compound term "Group intelligence tests" should be used consistently rather than "Group intelligence testing."
