Digital curation is the process of collecting, organizing and sharing online content. There are several types of curation including aggregation, filtering, elevation and mash-ups. Effective curation adds value by providing context and analysis to help people discover new ideas and insights. It involves listening to various sources of information, analyzing what is relevant and valuable, and sharing in a way that enriches others. Examples of curation include news aggregators, blogs and social media sites that filter large amounts of content into focused collections.
