When clicking on a link, i.e. 11 A.R.S. 901, The entire Title 11 of the Arizona Revised Statutes will appear. 11 refers to the Title and 901 refers to the section of that title. The A.R.S. is divided into Titles, each Title has Chapters. Each Chapter has Articles. The Sections are under the Articles. The Chapters (in dark grey bars) and Articles (in light grey bars) help keep the statutes (laws/code) arranged by topic. Chapters and Articles are not used when citing Arizona law. The Sections are in numeric order within the Title. The numbers of Chapters and Articles is irrelevant to finding the law - it is just used to place it in sequence. For Title 11, scroll until 11-901 appears. In this instance, you will scroll down to find Chapter 7 - Intergovernmental Operations. Article 1 is about public libraries. 11-901 is about the establishment and maintenance of public libraries. The legal citation for the law about county librarian certification would be 11 A.R.S. 908 (Title 11 of the Arizona Revised Statutes Section 908). This will help you find the citations after clicking on the links.
