    Abstract
    This research contrasts two different conceptions, fields and pathways, of individual information behavior in context. These different approaches imply different relationships between actors and their information environments and, thus, encapsulate different views of the relationship between individual actions and contexts. We discuss these different theoretical views, then empirically compare and contrast them. The operationalization of these conceptions is based on different analytic treatments of the same raw data: a battery of three questions based on respondent's unaided recall of the sources they would consult for information on inherited cancers, a particularly rich information seeking problem. These operationalizations are then analyzed in a nomological network of related concepts drawn from an omnibus survey of 882 adults. The results indicated four clusters for fields and 16 different pathways, indicating increased fragmentation of information environments, with different underlying logics and active ingredients, although the use of the Internet appears to be an emerging common theme. The analysis of the nomological network suggests that both approaches may have applications for particular problems. In the implications, we compare and contrast these approaches, discussing their significance for future methodological, analytical, and theoretical developments.

    Abstract
    The authors describe the development of processes and methods for user-centered access to collections of information. The implementation of this general model uses a standard terminology to represent the information collection and a set of possibly overlapping user domains to represent a social network. The goal of the implementation is to provide access to the terminology that is tailored to the needs of specific combinations of user domains. A pilot study using the Metathesaurus of the Unified Medical Language System and the user domains of consumer, radiologist, ophthalmologist, and family medicine physician was conducted by clustering terms across these domains. In three of the domains, consumer, radiologist, and ophthalmologist, we extracted terms from sources with user-warrant-- unpublished, work-related documents (e.g. clinical notes or email messages). For all four domains we extracted terms from sources with literary-warrant-- published documents (e.g. scientific journal articles or patient information pamphlets. For the clustering, the authors used a standard minimum spanning tree clustering algorithm with a weighted binary vector distance. The clustering algorithm produced clusters of quasi-synonyms and provided an alternative way to view the terms in the Metathesaurus
