    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
    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.
