Source structure refers to the organization and layout of information sources in a research area or field. This includes how sources are categorized, indexed, and presented to researchers for easy access and retrieval. Source structure plays a crucial role in helping researchers navigate through vast amounts of information and find relevant resources for their studies. It can also influence the way in which information is disseminated, shared, and consumed within a particular research area. Effective source structure can enhance the visibility and impact of research publications, while poor source structure can hinder the discoverability and accessibility of valuable information. Researchers and information professionals often work together to improve source structure through strategies such as database design, metadata tagging, and knowledge organization systems.
