An Information and Referral (I&R) resource database that describes the available programs and services needed by a community must be accurate, not just at the moment it is collected but as far as possible, at all subsequent moments. It must also be responsive to the creation of new programs and the closure of existing ones. Database maintenance is a standards-driven requirement for I&R services. This course describes the resource database maintenance process, including ways of handling agencies that are not responsive to requests for information. It outlines activities that help I&R services keep up-to-date on changes in the various sectors of health and human services, and stresses the importance of database security. This course is primarily for I&R Resource Specialists and managers. The course was written by AIRS staff member, Clive Jones, a former President of InformCanada, who is responsible for the AIRS Certification Program, in addition to assisting with training and standards development. It was adapted from material within The ABCs of I&R (copyright AIRS). AIRS is the nonprofit Alliance of Information and Referral Systems at www.airs.org.
