Knowledge and the library It was not until the development of monastic libraries in Europe around 1200 that humanity amassed in a single place what approached the collective wisdom and knowledge of the age. Libraries may be exchanges of information and market places for ideas but they are also the buildings which contain the bulk of human knowledge. Or, at least they were until the electronic digitally stored information revolution of the 1980s. Now knowledge is virtually everywhere; it has broken free of the constraint of buildings. Today if you were today to destroy all theworld’s libraries, it is unlikely that more than 20% of human knowledge would be lost. Certainly, a large amount of archival material would disappear forever, but a substantial volume of knowledge would survive. If a library is a repository of knowledge, this is now just one of its functions. The library’s prime function is now making that knowledge available and encouraging exchange and reflection upon it. Electronic knowledge is nowadays available to everybody – in the home, workplace, airport terminal, school, and so on. The Internet has liberated the library; nevertheless, it has not removed the justification for library facilities. (www.sciencedirect.com/science/article/pii/B978185617619410017X. Adaptado)

An increasing body of evidence suggests that the time we spend on our smartphones is interfering with our sleep, self-esteem, relationships, memory, attention spans, creativity, productivity and problem-solving and decision-making skills. But there is another reason for us to rethink our relationships with our devices. By chronically raising levels of cortisol, the body’s main stress hormone, our phones may be threatening our health and shortening our lives. If they happened only occasionally, phone-induced cortisol spikes might not matter. But the average American spends four hours a day staring at their smartphone and keeps it within arm’s reach nearly all the time, according to a tracking app called Moment. “Your cortisol levels are elevated when your phone is in sight or nearby, or when you hear it or even think you hear it,” says David Greenfield, professor of clinical psychiatry at the University of Connecticut School of Medicine and founder of the Center for Internet and Technology Addiction. “It’s a stress response, and it feels unpleasant, and the body’s natural response is to want to check the phone to make the stress go away.” But while doing so might soothe you for a second, it probably will make things worse in the long run. Any time you check your phone, you’re likely to find something else stressful waiting for you, leading to another spike in cortisol and another craving to check your phone to make your anxiety go away. This cycle, when continuously reinforced, leads to chronically elevated cortisol levels. And chronically elevated cortisol levels have been tied to an increased risk of serious health problems, including depression, obesity, metabolic syndrome, Type 2 diabetes, fertility issues, high blood pressure, heart attack, dementia and stroke.
