This bibliography presents a series of studies that focus on the topic of networks and on the manner in which they have been considered in the literature. Each section of the bibliography provides a working set of references for one of the five major areas of research in which network analysis has been used. The first section deals primarily with specifying the physical structure of networks. Theoretical work describing various relationships between nodes and arcs are listed as well as more empirical work that has utilized and extended this initial body of theory. The second section presents material dealing with the general problem of optimizing flows through a given network. The third section considers theoretical work that has been done to enumerate the total number of possible graphs of a system, given a set of nodes and a set of arcs. The fourth section looks at applied studies that use the theory of graphs in an attempt to derive "optimal" networks. Finally, the last section presents a series of studies that deal with the problem of seeking optimal routes through a network. (Author/DN)
