Abstract
The need to improve information access on the Web has resulted in Illinois’ implementation of lexicographer Dr. Jessica Milstead’s subject tree for the Find-It! Illinois Program. In 1999, when the Illinois State Library joined four other states in implementing a state Government Information Locator Service (GILS) project, developing a controlled vocabulary became an essential component for maximizing retrieval of government information. Furthermore, application of library cataloging tools such as the Library of Congress Subject Headings (LCSH) is insufficient for online retrieval. An analysis of the structure and content of Dr. Milstead’s subject tree reveals the importance of new tools for improving online access methods. Illinois’ implementation of Dr. Milstead’s subject tree exposed the interest for nationwide application. The Illinois subject tree has been named the “Jessica Tree” to convey its expanded utility. The national adoption of a controlled vocabulary for retrieving state government information online will require collaboration among all states, so that the vision of a Find-It! America can be actualized.
