We live in an era of big data where information can be found almost everywhere. Hence, Content Curation is necessary to filter all the useful information from all over the web. DGIST has developed our own curation platform named "D-curation (http://curation.dgist.ac.kr)" to manage and share social media content with users and other librarians. In this presentation, DGIST Library demonstrates how libraries face new challenges in relation to social media curation and share our experimental ways for the last two years with colleagues.
