    Abstract
    Communcation theory attempts to systematise the knowledge generated in this field. Problems result from the variety of approaches used, based on sociology and semiotics; and from its roots in socio-historical developments, which have given rise to numerous schools of thought in the 20th century. These can be grouped thematically to provide a global framework, comprising: the communication process; messages; reception; and the social production of communication. Establishing common links between these partial views is one path towards developing an overall theory but this negates the innate complexity which is the essence of communication

    Abstract
    SIPORbase, the System for Indexing in Portuguese, was developed by the National Library of Portugal, based on the LCSH. In contrast to the Brunet-Parguez system used in France, SIPORbase is a coextensive indexing language. Its initial application in 1989 to current bibliography has been extended to the collection of codices. Experience with manuscripts only indicates a high degree of relevance in retrieval, from the several hundred subject headings created so far
