This document was developed by the ASCLA Standards Review Subcommittee not only to endorse librarians in their efforts to establish very detailed crisis management procedures for their workplaces, but also to endorse librarians' efforts to develop the expertise to avert crises and arrive at successful library experiences for people with mental illnesses. Although public and school libraries are more likely to provide daily service to individuals who have mental illnesses, all librarians should be aware of the information needs of these patrons and be prepared to meet them.
