Special libraries are information centers that focus on specific subjects or serve particular user groups. They can be found in various settings, such as corporations, government agencies, museums, and universities. Unlike public or academic libraries, special libraries curate collections tailored to the needs of their users, often including specialized databases, rare documents, and industry reports. These libraries support research and decision-making by providing access to unique resources and expert assistance. They may also offer services like information retrieval, data analysis, and training in research methods. Examples of special libraries include law libraries, medical libraries, and corporate libraries.
