Fulfilling the Second Objective in the Online Catalog: Schemes for Organizing Author and Work Records into Usable Displays

Allyson Carlyle

An analysis of the requirements of the second objective of the catalog shows that it has two components, a retrieval component and a display component, and that it may be interpreted broadly to include related works and works about a work or author. Two schemes are investigated for their contributions to the creation of online catalog displays that meet second objective requirements. First, the catalog filing rule scheme is analyzed to show that author and work displays in card catalogs have been composed of many groups or classes of materials that may also be used to create organized displays in online catalogs. The groups used in the filing rule scheme are based on relationships among items. Second, a scheme based on Tillett's bibliographic relationship taxonomy is proposed to discover additional types of relation-ships that may be used to group records in online catalog displays. Finally, a new scheme for the creation of organized displays in online catalogs is proposed. it incorporates elements from both the filing rule scheme and the bibliographic relationship taxonomy to create displays that meet the requirements of the second objective more fully than either scheme does alone.

Chemistry Journal Use and Cost: Results of a Longitudinal Study

Tina E. Chrzastowski and Brian M. Olesko

Journal-use studies were conducted in the University of Illinois at Urbana-Champaign Chemistry Library in 1988, 1993, and most recently in 1996. Between 1988 and 1996, the cost of purchasing the journal collection rose 66.9% while use of the collection rose 34.2%. These increases occurred during the cancellation of over 180 chemistry journals between 1988 and 1996. The data point to a collection with obvious "top" journals that generate most of the use. While the data confirm the 80/20 rule (84% of use was generated by the top 100 journals in 1996, approximately 20% of the journal collection), journal use is even more focused toward the top: approximately 40% of all use in 1996 was generated by the top 10 titles. Use of the top 10 journals rose 60% between 1988 and 1996, with nearly identical titles occupying the top 10 positions over 8 years. Longitudinal trends in journal use and cost are explored, recommendations are made for successful journal-use study methodologies, and time series, data-centered collection development is addressed.

Data Entry and the Economy of Offshore Information Production

Steven Ellis

In this article a review of the data-entry industry and the role information organizations, such as libraries, play in that industry is presented. Information organizations are participants in an economy of information production -- one that is becoming globalized. With this globalization, new production practices have emerged. However, research has been accumulating for some time that calls the labor practices of the data-entry industry into question. With these labor practices come ethical dilemmas for information professionals. It is therefore necessary for the information professions to come to an understanding of this emerging economy. It is argued that an ethics of data conversion can neither arise through ceasing production offshore nor from technological advances in data-entry technology. An ethics of information production must involve the cooperation of both producers and consumers alike.

The Adequacy of the Structure of the National Library of Medicine Classification Scheme for Organizing Pharmacy Literature

Elsa M. Lopez-Mertz

The National Library of Medicine Classification (NLMC) scheme was developed in 1946, using basic ideas from earlier schemes developed for organizing resources in support of teaching medicine and widely used in the United States for classifying information resources including pharmacy and pharmaceutics. The purpose of this study is to examine how the structure of the NLMC accommodates pharmaceutical literature and assess its adequacy. The author analyzed the NLMC numbers assigned to 1,979 monographs with bibliographic records. The analysis revealed that the structure of the NLMC brought together 42% of the literature in the sub-class QV 701-835 while another 41% was scattered throughout the NLMC scheme. Additionally, 17% was classified elsewhere in the Library of Congress Classification (LCC).
