This work suggests that better organization of existing sources of information available in Europe and better application of these sources to training can result in improved understanding of how information systems work, and it provides an annotated list of some of these sources. The guide opens with an introduction to public policy and urban planning in the context of developing countries, and explains that because this subject area is so focused and interdisciplinary it is difficult to locate information in a consistent manner; thus, the information needs of the people living in urban areas of developing countries are little known or catered to. Definitions for the field are explored, and the prospective users of information networks within this field are identified, e.g., academics and researchers, funding agencies, students in Europe, consultants, and planners in the third world. Subsequent sections of the guide describe the types of materials included as reference sources (e.g., people, grey literature, and geospatial databases), and then list the resources by international organization or geographic location (United Kingdom, Scandinavia, Germany, France, Italy, Eastern Europe and the Benelux countries) from which the resources originate. An appendix presents a prototype information network. (SD)
