This study examines the perspectives of Indian librarians on the use of publisher-assigned classification numbers. The research aims to understand the current methods of obtaining classification numbers, the challenges librarians face, and the potential benefits of having uniform classification numbers provided by publishers. Data were collected from 314 library professionals. Key findings indicate significant support for publisher-assigned classification numbers, perceived benefits in terms of time savings and improved cataloging efficiency, and strong advocacy for the involvement of Indian library associations in promoting standardized practices. The study concludes with policy recommendations to enhance cataloging consistency and efficiency in Indian libraries. © 2025 Elsevier B.V., All rights reserved.
