    Abstract
    This article describes an approach based on structuration theory (Giddens, 1979, 1984; Orlikowski, 1992, 2000) and communities of practice (Wenger, 1998) that can be used to guide investigation into the dynamics of online question and answer (Q&A) communities. This approach is useful because most research on Q&A sites has focused attention on information retrieval, information-seeking behavior, and information intermediation and has assumed uncritically that the online Q&A community plays an important role in these domains of study. Assuming instead that research on online communities should take into account social, technical, and contextual factors (Kling, Rosenbaum, & Sawyer, 2005), the utility of this approach is demonstrated with an analysis of three online Q&A communities seen as communities of practice. This article makes a theoretical contribution to the study of online Q&A communities and, more generally, to the domain of social reference.

    Abstract
    Purpose - The purpose of this paper is to examine the quality of answers on the Wikipedia Reference Desk, and to compare it with library reference services. It aims to examine whether Wikipedia volunteers outperform expert reference librarians and exemplify the paradox of expertise. Design/methodology/approach - The study applied content analysis to a sample of 434 messages (77 questions and 357 responses) from the Wikipedia Reference Desk and focused on three SERVQUAL quality variables: reliability (accuracy, completeness, verifiability), responsiveness, and assurance. Findings - The study reports that on all three SERVQUAL measures quality of answers produced by the Wikipedia Reference Desk is comparable with that of library reference services. Research limitations/implications - The collaborative social reference model matched or outperformed the dyadic reference interview and should be further examined theoretically and empirically. The generalizability of the findings to other similar sites is questionable. Practical implications - Librarians and library science educators should examine the implications of the social reference on the future role of reference services. Originality/value - The study is the first to: examine the quality of the Wikipedia Reference Desk; extend research on Wikipedia quality; use SERVQUAL measures in evaluating Q&A sites; and compare Q&A sites with traditional reference services.
