As the technological environment changes and libraries assume new and more active roles in their institutions, the traditional library hierarchy ceases to be an effective organizational structure. Guided by theories that emphasize teamwork, quality, and employee empowerment and participation, libraries are developing flatter, more networked organizations. The Health Sciences Library at Columbia University in New York, New York, recently underwent a reorganization in an effort to become a more resilient, more flexible organization. The process was beneficial overall. While some errors and confusion occurred, these are seen as opportunities for learning and evidence of the library's new atmosphere of creativity and experimentation.
