Abstract  

Citation analysis for evaluative purposes requires reference standards, as publication activity and citation habits differ considerably among fields. Reference standards based on journal classification schemes are fraught with problems in the case of multidisciplinary and general journals and are limited with respect to their resolution of fields. To overcome these shortcomings of journal classification schemes, we propose a new reference standard for chemistry and related fields that is based on the sections of the Chemical Abstracts database. We determined the values of the reference standard for research articles published in 2000 in the biochemistry sections of Chemical Abstracts as an example. The results show that citation habits vary extensively not only between fields but also within fields. Overall, the sections of Chemical Abstracts seem to be a promising basis for reference standards in chemistry and related fields for four reasons: (1) The wider coverage of the pertinent literature, (2) the quality of indexing, (3) the assignment of papers published in multidisciplinary and general journals to their respective fields, and (4) the resolution of fields on a lower level (e.g. mammalian biochemistry) than in journal classification schemes (e.g. biochemistry & molecular biology).

Abstract

Taking the interactive open access journal Atmospheric Chemistry and Physics as an example, this study examines whether Thomson Reuters, for the Journal Citation Reports, correctly calculates the Journal Impact Factor (JIF) of a journal that publishes several versions of a manuscript within a two-stage publication process. The results of this study show that the JIF of the journal is not overestimated through the two-stage publication process.

Abstract  

The database host STN International allows for extensive citation analysis in the SCISEARCH database (Science Citation Index Expanded) and in the CAplus database (Chemical Abstracts). Along with its powerful browsing, searching and analyzing facilities, STN International also features scripts. In this paper we examine the usefulness of the script language in the automation of citation analysis in SCISEARCH and CAplus.
