    Abstract
    This is the second part of a two-part article that examines 25 years of published research findings on end-user searching of online information retrieval (IR) systems. In Part 1, it was learned that people enter a few short search statements into online IR systems. Their searches do not resemble the systematic approach of expert searchers who use the full range of IR-system functionality. Part 2 picks up the discussion of research findings about end-user searching in the context of current information retrieval models. These models demonstrate that information retrieval is a complex event, involving changes in cognition, feelings, and/or events during the information seeking process. The author challenges IR researchers to design new studies of end-user searching, collecting data not only on system-feature use, but on multiple search sessions and controlling for variables such as domain knowledge expertise and expert system knowledge. Because future IR systems designers are likely to improve the functionality of online IR systems in response to answers to the new research questions posed here, the author concludes with advice to these designers about retaining the simplicity of online IR system interfaces.

    Abstract
    This research investigates how people's perceptions of information retrieval (IR) systems, their perceptions of search tasks, and their perceptions of self-efficacy influence the amount of invested mental effort (AIME) they put into using two different IR systems: a Web search engine and a library system. It also explores the impact of mental effort on an end user's search experience. To assess AIME in online searching, two experiments were conducted using these methods: Experiment 1 relied on self-reports and Experiment 2 employed the dual-task technique. In both experiments, data were collected through search transaction logs, a pre-search background questionnaire, a post-search questionnaire and an interview. Important findings are these: (1) subjects invested greater mental effort searching a library system than searching the Web; (2) subjects put little effort into Web searching because of their high sense of self-efficacy in their searching ability and their perception of the easiness of the Web; (3) subjects did not recognize that putting mental effort into searching was something needed to improve the search results; and (4) data collected from multiple sources proved to be effective for assessing mental effort in online searching.

    Abstract
    An experimental online catalog was developed that provided searchers with several different subject searching strategies. Analyses of retrieval test data suggest that searchers expect alphabetical searches to provide lists of assigned subject headings conceptually related to their topics of interest. System designers can now respond to their expectation by incorporating LCSH-mr in online catalogs

    Abstract
    This is the first part of a two-part article that reviews 25 years of published research findings on end-user searching in online information retrieval (IR) systems. In Part 1 (Markey, 2007), the author seeks to answer the following questions: What characterizes the queries that end users submit to online IR systems? What search features do people use? What features would enable them to improve on the retrievals they have in hand? What features are hardly ever used? What do end users do in response to the system's retrievals? Are end users satisfied with their online searches? Summarizing searches of online IR systems by the search features people use everyday makes information retrieval appear to be a very simplistic one-stop event. In Part 2, the author examines current models of the information retrieval process, demonstrating that information retrieval is much more complex and involves changes in cognition, feelings, and/or events during the information seeking process. She poses a host of new research questions that will further our understanding about end-user searching of online IR systems.

    Abstract
    In the DDC Online Project, subject searching and browsing of DDC schedules and relative index were featured in an experimental online catalog. The effectiveness of this DDC in an online catalog was tested in online retrieval experiments at four participating libraries. These experiments provided data for analyses of subject searchers' use of a library classification in the information retrieval environment of an online catalog. Recommendations were provided for the enhancement of bibliographic records, online catalogs, and online cataloging systems with a library classification. In this paper, subject searchers' use of the subject outline search capability of the experimental online catalog is described. This capability was unique to the experimental online catalog and all other online catalogs, because it referred searchers to online displays of the classification schedules based on their entry of subject terms. Failure analyses of subject outline searches demonstrated its specific strenghts and weaknesses. Users' postsearch interview comments highlighted their experiences and their satisfaction with this search. Based on the failure analyses and users' interview comments, recommendations are provided for the improvement of the subject outline search in online catalogs.

    Abstract
    This paper examines the forty-year history of online use of classification systems. Enhancing subject access was the rationale for obtaining support to conduct research in classification online and for incorporating classification into online systems. Catalogers have been the beneficiaries of most of the advances in classification online and operational online systems are now able to assist them in class number assignment and shelflisting. To this day, the only way in which most end users experience classification online is through their online catalog's shelflist browsing capability. The author speculates on the reasons why classification online never caught on as an end user's tool in online systems. Both the information industry and the library and information science community missed the opportunity to lead the charge in the organization of Internet resources; however, OCLC, the publisher of the Dewey Decimal Classification, has made substantial improvements to the scheme that have increased its versatility for organizing Internet resources. Because mass digitization projects such as Google Print will solve the problem of subject access, the author makes recommendations for classification online to solve these vexing problems of end users: staging of access, retrieving the best material in response to user queries, and automatic approaches to finding additional relevant information for an ongoing search.
