Course Scope and Academic Rigor in BLIS-224: Library and Information Science

BLIS-224: Library and Information Science is a core component of IGNOU’s Bachelor’s Programme in Library and Information Science (BLIS), meticulously designed to equip students with foundational expertise in cataloguing, classification systems, and modern information management. This course bridges traditional library practices with contemporary digital frameworks, emphasizing the Dewey Decimal Classification (DDC) and Library of Congress Classification (LCC), alongside automated cataloguing standards like AACR2. Students explore information retrieval theories, digital library architectures, and ethical dimensions of information dissemination—preparing them for both academic and professional roles in libraries, archives, and knowledge-based organizations. The syllabus aligns with IGNOU’s CBCS curriculum, ensuring relevance to current industry standards and research trends.
