    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.

    Abstract
    The structure and use of the classification for books on the amazon.com website are described and analyzed. The contents of this very large website are changing constantly and the access mechanisms have the main purpose of enabling searchers to find books for purchase. This includes finding books the searcher knows about at the start of the search, as well as those that might present themselves in the course of searching and that are related in some way. Underlying the many access paths to books is a classification scheme comprising a rich network of terms in an enumerative and multihierarchical structure.
