Abstract
Extensive literatures exist on information searching theory and techniques, as well as on the Bradford Distribution. This distribution, also known as "Bradford's Law of Scattering," tells us that information on a subject is dispersed in a characteristic and robust pattern that appears consistently across many different environments. This pattern may be expected to have important implications for information searching theory and techniques. Yet these two research literatures are rarely considered in relation to each other. It is the purpose of this article to distinguish three Bradford regions and speculate on the optimum searching techniques for each region. In the process, browsing, directed searching in databases, and the pursuit of various forms of links will all be considered. Implications of growth in size of a literature for optimal information organization and searching will also be addressed.
