    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
    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.
