    Abstract
    Argues that Beghtol's (2003) use of the terms "naive classification" and "professional classification" is valid because they are nominal definitions and that the distinction between these two types of classification points up the need for researchers in knowledge organization to broaden their scope beyond traditional classification systems intended for information retrieval. Argues that work by Beghtol (2003), Kwasnik (1999) and Bailey (1994) offer direction for the development of a classification of classifications based on the pragmatic dimensions of extant classification systems.

    Abstract
    Search statements in this revision process can be viewed as a 'move' in the overall search strategy. Very little is known about how end users develop and revise their search strategies. A study was conducted to analyse the moves made in 244 data base searches conducted by 26 medical students at the University of North Carolina at Chapel Hill. Students search INQUIRER, a data base of facts and concepts in microbiology. The searches were conducted during a 3-week period in spring 1990 and were recorded by the INQUIRER system. Each search statement was categorised, using Fidel's online searching moves (S. Online review 9(1985) S.61-74) and Bates' search tactics (s. JASIS 30(1979) S.205-214). Further analyses indicated that the most common moves were Browse/Specity, Select Exhaust, Intersect, and Vary, and that selection of moves varied by student and by problem. Analysis of search tactics (combinations of moves) identified 5 common search approaches. The results of this study have implcations for future research on search behaviours, for thedesign of system interfaces and data base structures, and for the training of end users

    Abstract
    In information science, classification systems are conventionally viewed as tools for representing knowledge in the universe of ideas, the human mind, or one or more sets of documents. In this view, developing and maintaining relationships and structures in classification schemes must primarily consider two abstract ingredients: i) a set of concepts for one or more domains; and ii) a (set of) unambiguous structure(s) to articulate the relationships that persist between the various concepts that comprise the classificatory structure. We contend that design decisions pertaining to the structure of a classification system consist of far more than simply creating links between the elements in a particular set of concepts. Ultimately, a simplistic tool view of classifications implies that the construction is little more than a technical task in a very narrow sense: that classificatory concepts are viewed as standard representations of what are assumed to be the central and/or important topics in the knowledge domain(s), and that there is i) an unambiguous Platonic ideal or universal consensus that determines how the links will be generated within a classificatory structure; or, conversely, ii) that there are no general structures and relationships available at all, but that only diverse individual knowledge structures exist, which cannot be reconciled into a general organization of knowledge

    Abstract
    Icons are graphic images with functional roles in human-computer interaction. They may be used as conceptual tools to represent the organization of information or as operators affecting an activity such as printing or moving to another document. An icon may represent its referent either as a sign, a purely arbitrary relationship that must be learned by the user; as a pictograph, a visual image of the object represented, or as an ideogram, whre the referent is not a concrete entity but an attribute, a set of attributes, or an abstract concept associated with the referent. The symbolicity of an icon reflects the drgree of representativeness that obtains between an icon and its referent(s). We propose to examine symbolic languages composed of sets of icons and to assess their effectiveness as classificatory structures in terms of: 1) representation of hierarchical structure; 2) level of symbolicity; 3) contexts that promote the capability of icons to represent organization; 4) relationship between an underlying metaphorical framework and iconic representation of the organization; 5) graphic elements of effective symbolic languages; and 6) social or cultural factors related to the effectiveness of icons
