Abstract Information overload is a problem that affects law librarians every workday. Information overload occurs when the receiver receives so much data that the receiver is unable to engage in higher levels of processing. Technology and cultural influences play a significant role in creating information overload. Law librarians are particularly susceptible to information overload due to the characteristics of their profession. We should care about information overload because it has lasting negative consequences for our profession. Even though information overload is a real problem with serious consequences, there are numerous ways to minimize information overload and its effects. 相似文献

Information overload interferes with our abilities to use information effectively. It represents a challenge in searching print as well as online collections. Academic librarians have developed strategies to help their patrons reduce the effects of information overload. This article provides best practices employed by academic librarians to reduce their users’ information overload. Five themes emerged in a review of the literature: information presentation, library instruction, user strategies, librarian roles, and software technologies. Information literacy instruction remains particularly important in combating information overload since the promotion of users’ research skills facilitates their search competencies. Research on information problem solving that focuses on metacognitive strategies may help decrease information overload among users searching digital libraries. 相似文献

With the increasing disclosure of public information and government data through information and communication technologies, along with the considerable privately generated data now available online, individuals have access to a huge volume of information. This “disintermediation” of (i.e., greater direct access to) public information may improve transparency and facilitate citizen engagement, but it may also overwhelm citizens not only with too much information but also by requiring them to take responsibility for gathering, assembling, and processing information. Despite the importance of effective information processing to successful use of available information, existing studies have not yet fully integrated this consideration into research on citizen use of e-government and open government data. Based on information processing theory—according to which individuals have a finite information processing capacity, which is affected not only by the quantity and quality of information but also by one's preferences for how information is presented—this study examined the effects of information presentation type (infographic versus text) on perceived information overload, along with the consequent effect of information overload on perceived website usefulness. We also investigated whether individual information processing propensity (visual or verbal) moderated the effect of information presentation type on perceived information overload. Our results showed that textual information tended to cause greater information overload, especially for those with a propensity for visual information processing, and that higher information overload was associated with a lower perception of website usefulness. Moreover, individual information propensity moderated the effect of information type on perceived information overload; people with visual information processing propensity were more strongly affected by the presentation of textual information. We discuss the implications of our findings for improving the communication of policy information through government websites. 相似文献

Based on the information-as-coping perspective, we provided a theoretical framework to understand how the quality of government information and citizens' partisanship impact citizens' wellbeing in terms of satisfaction with life and anxiety during COVID-19. With survey data from 705 respondents in Indonesia, we found that government information quality is of vital importance in helping citizens get ready to fight the pandemic, as well as lowering their anxiety. Our results show that higher information quality leads to a higher ability to respond quickly to the crisis, as well as a reduced level of information overload. While partisanship is a significant predictor of information overload, it had no significant impact on perceived quick response ability. Quick response ability and information overload, in turn, predict anxiety and citizen's satisfaction with life. 相似文献
