- Abstract
- How are library professionals who do research about bibliographic organization using electronic resources (e-resources) in their journal articles? Are they keeping pace with the use of e-resources outside the library world? What are the e-resources most used in their research? This article aims to address these and other questions by analyzing bibliographical references/notes in articles in Cataloging and Classification Quarterly (CCQ) for every other year from 1994 to 2004.

- Abstract
- By analyzing the source documents and their references by classification systems researchers in the world, this paper presents core journals of the field during the period 1981-1990. The findings show that journal literature in this study confirms to Bradford's law and provides 'Cataloging and classification quarterly (CCQ)' as the most productive journbal, 'Library resources and technical services (LRTS)' as the most frequently cited journal of the field and 'Knowledge organization (KO)', formerly 'International classification (IC)' as the second productive and frequently cited journal of the field. The principal journals publishing source items differs from those used as reference sources of the field. The high-ranked international journals over the years are clearly those to be acquired to obtain the greatest coverage of the field for the least cost
