    Digital Repositories and Open Access: Information Without Limits

    For many libraries, the Digital Repository has become the main storage center for materials created by the community they serve. Such materials can include important historical records, local newspapers, community newsletters, as well as articles, presentations, data sets, images, videos and other multimedia items. In this way, the repository takes on a central role in placing free, open access materials into the hands of the public. While many repositories are currently managed by universities, their benefits reach beyond the walls of academia to include K-12 students as well as the public at large. Thus, all librarians are encouraged to utilize the materials housed in repositories during their educational programming. Doing so has the advantage of providing reliable information at no cost to their patrons while at the same time creating ties between the university and the local community. Furthermore, the use of open access materials during instruction sessions and reference interactions presents the librarian with many opportunities to discuss the increased importance of fair use and intellectual property issues

    Rapid and highly variable warming of lake surface waters around the globe

    In this first worldwide synthesis of in situ and satellite-derived lake data, we find that lake summer surface water temperatures rose rapidly (global mean = 0.34°C decade-1) between 1985 and 2009. Our analyses show that surface water warming rates are dependent on combinations of climate and local characteristics, rather than just lake location, leading to the counterintuitive result that regional consistency in lake warming is the exception, rather than the rule. The most rapidly warming lakes are widely geographically distributed, and their warming is associated with interactions among different climatic factors - from seasonally ice-covered lakes in areas where temperature and solar radiation are increasing while cloud cover is diminishing (0.72°C decade-1) to ice-free lakes experiencing increases in air temperature and solar radiation (0.53°C decade-1). The pervasive and rapid warming observed here signals the urgent need to incorporate climate impacts into vulnerability assessments and adaptation efforts for lakes

    Theft and Vandalism of Books, Manuscripts, and Related Materials in Public and Academic Libraries, Archives, and Special Collections

    While book theft and vandalism in public and academic libraries, as well as archives and special collections, are not considered a modern problem, they have, in recent years, become a matter of increasing concern to these institutions. Easy access to materials housed in multi-story libraries difficult to effectively supervise; the online presence of archives and special collections detailing the contents of their collections to attract researchers and visitors; and a seemingly growing number of persons willing to express their personal convictions and beliefs by removing or destroying items from public and private collections, are among the primary reasons for the ongoing loss of materials. This research paper examines the motives behind book theft and vandalism, summarizes existing security measures, and offers suggestions for theft and vandalism prevention

    Risk factors for severe outcomes following 2009 influenza A (H1N1) infection: a global pooled analysis

    Background Since the start of the 2009 influenza A pandemic (H1N1pdm), the World Health Organization and its member states have gathered information to characterize the clinical severity of H1N1pdm infection and to assist policy makers to determine risk groups for targeted control measures. Methods and Findings Data were collected on approximately 70,000 laboratory-confirmed hospitalized H1N1pdm patients, 9,700 patients admitted to intensive care units (ICUs), and 2,500 deaths reported between 1 April 2009 and 1 January 2010 from 19 countries or administrative regions—Argentina, Australia, Canada, Chile, China, France, Germany, Hong Kong SAR, Japan, Madagascar, Mexico, the Netherlands, New Zealand, Singapore, South Africa, Spain, Thailand, the United States, and the United Kingdom—to characterize and compare the distribution of risk factors among H1N1pdm patients at three levels of severity: hospitalizations, ICU admissions, and deaths. The median age of patients increased with severity of disease. The highest per capita risk of hospitalization was among patients <5 y and 5–14 y (relative risk [RR] = 3.3 and 3.2, respectively, compared to the general population), whereas the highest risk of death per capita was in the age groups 50–64 y and ≥65 y (RR = 1.5 and 1.6, respectively, compared to the general population). Similarly, the ratio of H1N1pdm deaths to hospitalizations increased with age and was the highest in the ≥65-y-old age group, indicating that while infection rates have been observed to be very low in the oldest age group, risk of death in those over the age of 64 y who became infected was higher than in younger groups. The proportion of H1N1pdm patients with one or more reported chronic conditions increased with severity (median = 31.1%, 52.3%, and 61.8% of hospitalized, ICU-admitted, and fatal H1N1pdm cases, respectively). With the exception of the risk factors asthma, pregnancy, and obesity, the proportion of patients with each risk factor increased with severity level. For all levels of severity, pregnant women in their third trimester consistently accounted for the majority of the total of pregnant women. Our findings suggest that morbid obesity might be a risk factor for ICU admission and fatal outcome (RR = 36.3). Conclusions Our results demonstrate that risk factors for severe H1N1pdm infection are similar to those for seasonal influenza, with some notable differences, such as younger age groups and obesity, and reinforce the need to identify and protect groups at highest risk of severe outcomes
