The question asks about the individual who was the first to develop the Universal Decimal Classification (UDC) system. Understanding the history of library classification is key to identifying the correct pioneer.

Universal Decimal Classification (UDC) Overview

The Universal Decimal Classification (UDC) is a sophisticated international classification system used for organizing information in various types of documents and institutions worldwide, especially libraries. It is a highly detailed and flexible system designed to classify knowledge across all fields.

Paul Otlet's Role in UDC Development

The development of the Universal Decimal Classification (UDC) system is primarily credited to Belgian lawyers and bibliographers Paul Otlet and Henri La Fontaine. They began working on UDC in the late 19th century, specifically around 1895, as a collaborative effort.

• Foundation: UDC was initially based on the widely recognized Dewey Decimal Classification (DDC) system, developed by Melvil Dewey. Otlet and La Fontaine adapted and expanded DDC to create a more comprehensive and internationally applicable system.
• Purpose: Their goal was to create a universal classification scheme to organize the vast amount of information collected at the International Institute of Bibliography (IIB) in Brussels, which later became the FID (International Federation for Information and Documentation).
• Innovation: They introduced several innovations, such as auxiliary tables for common facets like language, form, place, and time, making UDC more analytical and capable of expressing complex subjects.

Distinguishing Other Contributions

While the other options are prominent figures in library science, they are not credited with the primary development of UDC:

• Melvil Dewey: He developed the Dewey Decimal Classification (DDC), which served as the foundation for UDC, but he did not develop UDC itself.
• H.E. Bliss: Henry Evelyn Bliss developed the Bliss Bibliographic Classification (BC), another significant library classification system, but distinct from UDC.
• E.C. Richardson: Ernest Cushing Richardson was an influential American librarian and library theorist, known for his work on classification and bibliography, but he was not involved in the development of UDC.

Concluding the UDC Developer

Based on the historical facts of library science and classification systems, Paul Otlet was the first to develop UDC, working in collaboration with Henri La Fontaine. Their work laid the foundation for one of the most enduring and widely used international classification systems.
