    Abstract
    Reports results of 2 studies to determine if structured abstracts offer any advantage to users in terms of whether they are easier to search. In study 1, using a specially prepared electronic database of abstracts in either their original format or the structured format, 52 users were asked to find the answers to 2 questions for each of 8 abstracts in traditional format followed by 2 questions for each of 8 abstracts set in the structured format. Time and error data were recorded automatically. In study 2, using a printed database, 56 users were asked to to find 5 abstracts that reprted a particular kind of study and then find 5 more references that reported another kind of study. In study 1 users performed significantly faster and made fewer errors with structured abstracts but there were some unexplainable practice effects. In study 2, the users again performed significantly faster and made fewer errors with structured abstracts. However, there were asymmetrical transfer effects: users who responded first to the structured abstracts responded more quickly to the following traditional abstracts than did those users who responded first to the traditional abstracts. Nevertheless, the overall findings support the hypothesis that it is easier for user to search structured abstracts than it is to search traditional abstracts
