Systems librarianship, when merged with the position of informationist, evolves into the identity of the systems informationist in the hospital setting. The Health Sciences Library at Geisinger has successfully implemented a systems informationist role within an open systems framework. The duties of the systems informationist are framed here using: input for information-seeking behavior; throughput of clinical support for patient care; output by user experience in research and education; and feedback to elevate operational excellence. This case report contributes a focused approach to systems librarianship, providing examples for other hospital libraries that may be interested in developing their own Systems Services.
