Public relations is the process of invoking a public understanding of goodwill toward the public library system. A public relations program is an integral part of the library system’s strategic plan. A plan builds good customer relations, and contributes to a positive relationship with the media, businesses, and other local government agencies/organizations.  It is important to remember that the public relations efforts of the library system have to be continuous.  A public relations plan should be written by the director or his/her designee, approved by the administrative board of trustees, and reviewed on an annual basis.
