International Journal of Information Studies Sharadamma C A, Hemavathi B N 18 2 2026 https://doi.org/10.6025/ijis/2026/18/2/49-63 https://www.dline.info/ijis/fulltext/v18n2/ijisv18n2_1.pdf In the rapidly evolving digital environment, technological skills are essential for librarians to effectively utilize tools such as Social Networking Sites (SNS) and Open Educational Resources (OER). Librarians' digital literacy acts as a bridge between technology and users, enabling efficient access to information resources. This study examines the utilization of SNS and OER among librarians working in Government First Grade Colleges (GFGCs) and State Government Universities in Karnataka. A survey of 379 librarians was conducted using structured questionnaires distributed through both online and offline modes. The findings reveal that 275 (72.55%) librarians actively use SNS, with WhatsApp (144, 52.36%) and YouTube (65, 23.63%) emerging as the most widely used platforms. SNSs are primarily used for marketing library services (155, 56.36%), promoting libraries (134, 48.72%), and engaging users (110, 40%). However, the study indicates relatively low participation in research collaboration and academic networking, with only 106 (27.96%) respondents using academic social networking platforms. Awareness of Open Educational Resources (OER) is high among respondents, with 292 (77.04%) reporting familiarity with these initiatives. Platforms such as e-PG Pathshala, SWAYAM, UGC-MOOCs, and Shodhganga are widely utilized, while resources like Ekalavya, E-BIDYA, and Sakshat show comparatively lower adoption levels. The study highlights the need for enhanced awareness, training, and institutional support to optimize the use of SNS and OER for improving library services and user engagement in higher education institutions.
