This study looks at how the relationship between libraries and social media is changing in the digital information ecosystem. Because platforms like Facebook, Instagram, and Twitter are growing so quickly, libraries have changed from being places to store information to being places where people can find and share information. Libraries can use social media to get people more involved, promote their services, share information, and build online communities. The study shows how libraries use these sites for marketing, teaching people how to use technology, and talking to users in real time. It also talks about problems like how to trust information, privacy issues, and the need for librarians to get professional training. The study employs a conceptual and analytical methodology to assess the influence of social media integration on library services. It concludes that strategic planning and ethical considerations must be adequately addressed for effective use of social media to significantly improve the accessibility, visibility, and relevance of libraries in the digital age.
