    Abstract
    Reports a comparative study carried out at Sheffield University to compare the performance of 2 manual indexes and 3 related online databases in the retrieval of records in the technological subject of: Cathodic protection of concrete structures. The manual sources were: Engineering Index and Current Technology Index; and the online databases were: COMPENDEX, NTIS and SCISEARCH. Performance was measured in terms of relative recall and prescision. While online searches showed some considerable advantages over manual searches, the manual sources showed some considerable advantages over manual searches, the manual sources still manifested some qualities which render them valuable. Emphasizes the selection of databases on the basis of a compromise between high recall and high precision, and ultimately between both of these factors and cost

    Abstract
    Highlights the major trends in information needs and use in a survey of the literature from the later 1940s to the present time. The shortcomings of early studies, particularly questionnaire surveys, are found to be defective methodology and shallow conceptualization. More sophisticated and refined techniques were introduced in the mid 1960s leading to more empirical research and to the study of informal transmission systems. The 1970s still revealed a need for greater conceptualization. New paradigms and approaches emerged in the 1980s leading to considerations of the environment in which information is used and distinctions between the cognitive and social aspects of information.
