    Abstract
    One difficulty faced by students on many information management courses is the lack of any attempt to teach concepts of information. Therefore, if a core module does not fit in with a student's existing concept of information, it can make it hard for the student to recognise the relevance of that module. This paper addresses that problem by summarising concepts of information, and by presenting a simple model that attempts to unite the various concepts listed. The model is based on the idea that the meaning in a message depends on the context in which the message originated (the authorial context), and the context in which it is interpreted (the readership context). Characteristics of authors, readers and messages are discussed. The impact of the 'knowledge' of 'information' users, and of their community, is considered. Implications of the model are discussed. A definition of information is suggested, which attempts to encapsulate the nature of information implied by the model.

    Abstract
    Purpose - The purpose of this paper is to examine the association between information and boundaries. Life depends on boundaries; but in order to survive an organism needs to make decisions based on an interpretation of the environment beyond its boundaries: it therefore needs information. Design/methodology/approach - The paper explores the evolution of physical, social and cultural boundaries and considers how they have shaped ways in which information is gathered and used. Findings - Several evolutionary developments are reviewed. The paper argues that each one has generated an additional boundary and that each new boundary has affected the information needs within it. The paper argues that all living things use information to help address three fundamental concerns: "Where can the energy needed to stay alive be found?", "How can it be stored?", and "How can use of energy be reduced?" Because these questions are fundamental at a biological level they are also fundamental at a societal level. One way to increase energy efficiency was for organisms to grow larger. This brought risks which were alleviated by the evolution of better information gathering and processing tools. Amongst these tools were the means to communicate, which afforded the evolution of social boundaries. Originality/value - This is a new perspective on a topic of growing interest in information science and demonstrates further the significance of information as a factor in the shaping of life.

    Abstract
    Purpose The purpose of this paper is to investigate the relationship between preferred choice of school subject and student information behaviour (IB). Design/methodology/approach Mixed methods were employed. In all, 152 students, teachers and librarians participated in interviews or focus groups. In total, 1,375 students, key stage 3 (11-14 years) to postgraduate, responded to a questionnaire. The research population was drawn from eight schools, two further education colleges and three universities. Insights from the literature review and the qualitative research phase led to a hypothesis which was investigated using the questionnaire: that students studying hard subjects are less likely to engage in deep IB than students studying soft subjects. Findings Results support the hypothesis that preferences for subjects at school affect choice of university degree. The hypothesis that a preference for hard or soft subjects affects IB is supported by results of an analysis in which like or dislike of maths/ICT is correlated with responses to the survey. Interviewees' comments led to the proposal that academic subjects can be classified according to whether a subject helps students to acquire a "tool of the Mind" or to apply such a tool. A model suggesting how IB may differ depending on whether intellectual tools are being acquired or applied is proposed. Practical implications The "inner logic" of certain subjects and their pedagogies appears closely linked to IB. This should be considered when developing teaching programmes. Originality/value The findings offer a new perspective on subject classification and its association with IB, and a new model of the association between IB and tool acquisition or application is proposed, incorporating the perspectives of both teacher and student.

    Abstract
    Purpose - A common criticism of research into information seeking on the internet is that information seekers are restricted by the demands of the researcher. Another criticism is that the search topics, are often imposed by the researcher, and; particularly when working with children, domain knowledge could be as important as information-seeking skills. The research reported here attempts to address both these problems. Design/methodology/approach - A total of 15 children, aged 11 to 16, were each set three "think aloud" internet searches. In the first, they were asked to recall the last time they had sought information on the internet, and to repeat the search. For the second, they were given a word, asked to interpret it, then asked to search for their interpretation. For the third, they were asked to recall the last time they had been unsuccessful in a search, and to repeat the search. While performing each task, the children were encouraged to explain their actions. Findings - The paper finds that the factors that determined a child's ability to search successfully appeared to be: the amount of experience the child had of using the internet; the amount of guidance, both from adults and from peers; and the child's ability to explore the virtual environment, and to use the tools available for so doing. Originality/value - Many of the searches performed by participants in this paper were not related to schoolwork, and so some of the search approaches differed from those taught by teachers. Instead, they evolved through exploration and exchange of ideas. Further studies of this sort could provide insights of value to designers of web environments.

    Abstract
    The association between life and information is discussed. Information is considered to be "a stimulus which expands or amends the World View of the informed". Using this definition, the standard chain of evolutionary development is reconsidered. It is proposed that information was derived from the environment as a direct result of the evolution of organisms that used other organisms as a food source. Only with the evolution of sexual reproduction did it become necessary for organisms to be aware of others of the same species. It is argued that one of the consequences of the evolution of different sexes is that often, prospective mates had to evolve means of communication, making it possible for animals to expand their World Views by other means. Such reinterpretation of evolutionary thinking has numerous implications for the information scientist. Some of these are discussed.
