    Abstract
    The literature of the evaluation of Internet search engines is reviewed. Although there have been many studies, there has been little consistency in the way such studies have been carried out. This problem is exacerbated by the fact that recall is virtually impossible to calculate in the fast changing Internet environment, and therefore the traditional Cranfield type of evaluation is not usually possible. A variety of alternative evaluation methods has been suggested to overcome this difficulty. The authors recommend that a standardised set of tools is developed for the evaluation of web search engines so that, in future, comparisons can be made between search engines more effectively, and that variations in performance of any given search engine over time can be tracked. The paper itself does not provide such a standard set of tools, but it investigates the issues and makes preliminary recommendations of the types of tools needed

    Abstract
    The study of information needs has long be acknowlegded as one of the most important factors in the design of information services but has been hampered by the severe problem of designing user studies that will reliably measure them. Reviews the literature of previous research in this field, concluding that time and money are the chief constraints on information seeking behaviour. Describes a new observational technique for identifying the information needs of users and reports results of a small scale experiment to test the methodology. The observational technique involves the researcher being with the subject continuously throughout the day and observing their actions. The behaviour recorded was any action taken in order to answer a question. A small scale study was undertaken of 3 academics from the Psychology Department, University of Strathclyde, using the observational technique. The preferred technique of all the academics was to carry out their own research, followed by consultation with other individuals. One lecturer was a significantly heavier user of electronic media than the other two. The preferred physical locations of the information sources were personal collections and the University Library. One lecturer consistently used a wide range of sources while the other two strongly preferred to use personal contacts. Informal sources were found to be twice as popular as formal sources. A follow up questionnaire survey examined the possibility that previous training in the use of the library could explain the differences in the use of electronic information sources but results were found to be negative. Concludes that the new research tool developed for this type of study is both robust and likely to yield reliable information about user information needs
