Healthcare systems are complex organizations that patients and families may find difficult to navigate. MedlinePlus Go Local projects are assisting consumers in this navigation by developing directories of health services that are indexed by geographic area, types of services provided, and associated health issues. Librarians affiliated with healthcare systems can play a critical role in promoting their organization and assisting healthcare consumers in locating needed services by assisting Go Local projects in accurately indexing their organization and assisting with keeping the information up-to-date.
