"Transparency" has recently become a popular buzzword in the United States while its normative value has been revered for decades. However, scholarly research of antecedents and effects of transparency-the ability to "see inside" government-has arisen only recently. Transparency can provide residents with information that can promote more fruitful citizen participation and engagement. This chapter looks into one of the lesser studied of the five avenues of transparency, as presented by Piotrowski (2007): proactive dissemination. It reports on the proactive dissemination behaviors of New Jersey's 566 municipalities resulting from a content analysis of their websites. Model results are reported to provide understanding of various factors that are found to impact a municipality's posting behavior. Lastly, the author encourages future research to consider other ways to measure proactive dissemination, to include more governmental determinants for transparent behavior, and to explore whether or not transparency translates into greater citizen participation. © 2012, IGI Global.
