This paper analyzes: (1) the bibliographic access to publications in urban studies via printed secondary sources; (2) development and scope of classification systems and of vocabulary control for urban studies; and (3) currently accessible automated collections of bibliographic citations. Urban studies is defined as "an agglomeration of interdisciplinary approaches to common phenomena and/or problems that have come about as a result of urbanism and urbanization," and includes approaches to the understanding and/or solution of these problems. Secondary sources, most described in detail within the text, include indexes, bibliographies, retrospective sources, government publications, research and report literature, and review literature and current awareness sources. Specific examples from classification systems and the merits of the most important subject heading systems are discussed. Fifteen computerized data bases relevant to urban studies are described with accompanying bibliography. Lists of compared title coverage of urban studies periodicals in three indexes, and of most frequently cited journals, are appended. (Author/KP)
