    Abstract
    Reports results of a study to examine the performance of online catalogue searches involving personal names and to recommend improvements to the basic system approach to soliciting user queries and searching for them. The research questions addressed in the study wre: how online systems can chose searching approaches on their own that are likely to produce useful retrieval; how online systems solicit queries from users; and how users respond to an experimental online catalogue that prompts them for the different elements of their personal name queries. Improvements include: the implementation of a new design for online catalogue searching that features search trees; new methods for soliciting user queries bearing personal names; and enlisting the participation of online catalogue users in the evaluation of system prompts, instructions, and messages that request input from them

    Abstract
    Describes the comparative approach to system evaluation used in this research project which delegated the administartion of an online retrieval test to an experimental online catalogue to produce data for evaluating the effectiveness of a new subject access design. Describes the methods enlisted to sort out problem test administration, e.g. to identify out-of-scope queries, incomplete system administration, and suspect post-search questionnaire responses. Covers how w the researchers handled problem search administrations and what actions they would use to reduce or eliminate the occurrence of such administrations in future online retrieval tests that delegate control of retrieval tests to online systems
