    Abstract
    This study explores, in 3 steps, how the 3 main library classification systems, the Library of Congress Classification, the Dewey Decimal Classification, and the Universal Decimal Classification, cover human knowledge. First, we mapped the knowledge covered by the 3 systems. We used the "10 Pillars of Knowledge: Map of Human Knowledge," which comprises 10 pillars, as an evaluative model. We mapped all the subject-based classes and subclasses that are part of the first 2 levels of the 3 hierarchical structures. Then, we zoomed into each of the 10 pillars and analyzed how the three systems cover the 10 knowledge domains. Finally, we focused on the 3 library systems. Based on the way each one of them covers the 10 knowledge domains, it is evident that they failed to adequately and systematically present contemporary human knowledge. They are unsystematic and biased, and, at the top 2 levels of the hierarchical structures, they are incomplete.

    Abstract
    Nearly 25 years have elapsed since the last comprehensive measure of the percentage of academic libraries that employ the Dewey and Library of Congress systems of classification. To provide updated statistics, the researchers surveyed all 3793 academic libraries via their online catalogs. The findings indicate that the use of Dewey has declined over the past four decades. Teachers' Colleges and Community Colleges in particular have higher rates of Dewey use than large research or professional universities. This information may help support academic library reclassification decisions.
