    Abstract
    This article gives a cheerfully brief and undetailed account of how to make a faceted classification system, then describes information retrieval and searching on the web. It concludes by saying that facets would be excellent in helping users search and browse the web, but offers no real clues as to how this can be done.

    Abstract
    A fascinating, broad-ranging article about classification, knowledge, and how they relate. Hierarchies, trees, paradigms (a two-dimensional classification that can look something like a spreadsheet), and facets are covered, with descriptions of how they work and how they can be used for knowledge discovery and creation. Kwasnick outlines how to make a faceted classification: choose facets, develop facets, analyze entities using the facets, and make a citation order. Facets are useful for many reasons: they do not require complete knowledge of the entire body of material; they are hospitable, flexible, and expressive; they do not require a rigid background theory; they can mix theoretical structures and models; and they allow users to view things from many perspectives. Facets do have faults: it can be hard to pick the right ones; it is hard to show relations between them; and it is difficult to visualize them. The coverage of the other methods is equally thorough and there is much to consider for anyone putting a classification on the web.
