WCB Sayers
The question asks to identify the individual considered the first grammarian of library classification. A "grammarian" in this context refers to someone who codified or systematically established the fundamental rules and principles of a subject, much like a grammarian establishes the rules of language. In the field of library classification, this title is attributed to a specific figure for their foundational work.
WCB Sayers is widely regarded as the first grammarian of library classification. He was instrumental in articulating the theoretical underpinnings and systematic principles of classification schemes, particularly within the context of the British library system. His influential work, such as Introduction to Library Classification, published in 1918, provided a comprehensive overview and analysis of classification concepts. Sayers focused on the logical structure and theoretical basis of classification, moving beyond the mere creation of schemes to explaining the 'why' and 'how' of classification systems. His writings helped establish a theoretical framework for understanding classification, earning him the title of grammarian.
While other notable figures contributed significantly to library classification, their roles differ:
Therefore, based on the historical development of theoretical principles and systematic rules for library classification, WCB Sayers is recognized as the first grammarian in this domain.
