    ABSTRACT: We conducted a systematic review of the scientific literature from 1966 to 2005 to determine whether animals could provide early warning of a bioterrorism attack, serve as markers for ongoing exposure risk, and amplify or propagate a bioterrorism outbreak. We found evidence that, for certain bioterrorism agents, pets, wildlife, or livestock could provide early warning and that for other agents, humans would likely manifest symptoms before illness could be detected in animals. After an acute attack, active surveillance of wild or domestic animal populations could help identify many ongoing exposure risks. If certain bioterrorism agents found their way into animal populations, they could spread widely through animal-to-animal transmission and prove difficult to control. The public health infrastructure must look beyond passive surveillance of acute animal disease events to build capacity for active surveillance and intervention efforts to detect and control ongoing outbreaks of disease in domestic and wild animal populations.

    ABSTRACT: Purpose – The purpose of this paper is to introduce the Unalog software system, a free and open source toolkit for social book marking in academic environments. Design/methodology/approach – The history, objectives, features, and technical design of Unalog is presented, along with a discussion of planned enhancements. Findings – The Unalog system has been very useful for information sharing among members of the digital library community and a group of beta testers at Yale University, leading its developers to plan several new features and to capitalize on opportunities for integration with other campus systems. Originality/value – This paper describes a freely available toolkit, which can be used to provide new services through libraries to academic communities, and how those new services might be enhanced by merging the potential they offer for easier information sharing with long-standing practices of librarianship.

    ABSTRACT: Despite recognition that animals could be serving as sentinels for environmental risks to human health, there are no evidence-based guidelines for the use of animal sentinel data in human health decision making. We performed a systematic review of the animal sentinel literature to assess the evidence linking such events to human health. A search of MEDLINE identified peer-reviewed original studies of animals as sentinels for either chemical or biological environmental hazards. A limited search of the CAB and AGRICOLA databases was also performed. We classified a random sample of 100 studies from the MEDLINE search according to species, hazard, and health outcome examined; study methods; and linkages to human health. Animal sentinel studies were difficult to locate in MEDLINE because of a lack of adequate key words for this concept. We found significant limitations in the study methods used to investigate animal sentinel events. Clear linkages to human health were frequently absent. Studies of sentinel events in animal populations hold potential for the recognition and control of human environmental health hazards, yet a number of barriers exist to using such data for evidence-based human health decisions. There is a need for greater data sharing and cooperative research between human and animal health professionals regarding environmental hazards and health outcomes in animal and human populations.

    ABSTRACT: 'Library groupware' - a set of networked tools supporting information management for individuals and for distributed groups - is a new class of service we may choose to provide in our libraries. In its simplest form, library groupware would help people manage information as they move through the diversity of online resources and online communities that make up today's information landscape. Complex implementations might integrate equally well with enterprise-wide systems such as courseware and portals on a university campus, and desktop file storage on private individual computers. Ideally, successful library groupware should provide individuals and groups with a common set of information functions they may apply to any information they find anywhere. In this article we make a simple case for library groupware as a unifying service model across disparate information environments. We consider the distributed, personalised collection development model that groupware would serve, and propose an architectural model which might provide a first step in an evolutionary path from today's commonplace digital library services towards integrated library groupware.
