    Abstract
    This article gives an overview of the design and organisation of DutchESS, a Dutch information subject gateway created as a national collaborative effort of the National Library and a number of academic libraries. The combined centralised and distributed model of DutchESS is discussed, as well as its selection policy, its metadata format, classification scheme and retrieval options. Also some options for future collaboration on an international level are explored

    Abstract
    Although researchers have theorized the critical importance of classification in the organization of information, the classification approach seems to have given way to the alphabetical subject approach in retrieval tools widely used in libraries, and research an how users utilize classification or classification-like arrangements in information seeking has been scant. To better understand whether searchers consider classificatory structures a viable alternative to information retrieval, this article reports an a study of how 24 library and information science students used Yahoo! directories, a popular search service resembling classification, in completing an assigned simple task. Several issues emerged from the students' reporting of their search process and a comparison between hierarchical navigation and keyword searching: citation order of facets, precision vs. recall, and other factors influencing searchers' successes and preferences. The latter included search expertise, knowledge of the discipline, and time required to complete the search. Without a definitive conclusion, we suggest a number of directoons for further research.
