    Abstract
    Many information channels are available to students, but it is now clear how students select and use them. Reports results of a study of the information seeking behaviour of students at 2 US universities: the American University; and the District of Columbia University. The study aimed to investigate: the information channels used by students when they work on course related projects and how they select the channels; how they use ALADIN, an augmented OPAC that provides access to the holdings of the Washington Research Library Consortium and several commercial online databases; and how selected characteristics of students are related to their use of information channels. Students identified convenience and quality of data as the top 2 factors in their choice of information channel. Affirms the value of librarians and of formal information channels, suggests ways to augment the online catalogue, and reminds librarians that equal access to information technology does not necessarily lead to equal use

    Abstract
    This study investigated the effects of subject knowledge and search experience on novices' and experienced searchers' use of search tactics in online searches. Novice and experienced searchers searched a practice question and two test questions in the ERIC database on the DIALOG system and their use of search tactics were recorded by protocols, transaction logs, and observation. Search tactics were idetified from the literature and verified in 10 pretests, and nine search tactics variables were operationalized to describe the differences between the two searcher groups. Data analyses showed that that subject knowledge interacted with search experience, and both variables affected searchers' behavior in four ways: (1) when questions in their subject area were searched, experience affected searchers' use of synonymous terms, monitoring of the search process, and combinations of serch terms; (2) when questions outside their subject areas were searched, experience affected searchers' reliance on their own terminology, use of the thesaurus, offline term selection, use of synonymous terms, and combinations of search terms; (3) within the same experience group, subject knowledge had no effect on novice searchers; but (4) subject knowledge affected experienced searcher's reliance on their own language, use of the thesaurus, offline term selection, use of synonymous terms, monitoring of the search, and combinations of search terms. The results showed that search experience affected searchers' use of many search tactics, and suggested that subject knowledge became a factor only after searchers have had a certain amount of search experience
