[Sigcr-l] Mapping the knowledge covered by library classification systems

[chaim Zins]

Dear Colleagues,

The article, Mapping the knowledge covered by library classification
systems (JASIST 62(5), 877-901) has been published (May 2011) and is
online at: http://onlinelibrary.wiley.com/doi/10.1002/asi.21481/abstract
 The article is based on a 2-year study conducted at UNESP - Marilia,
SP  (Brazil/Israel)

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.

If you have any critical reflections or practical suggestions please
share them with us and we will publish and respond in the FORUM page.
