    Abstract
    Studies the quality of subject indexing by Chemical Abstracts Indexing Service by confronting authors with the particular indexing terms attributed to their computer, for 270 articles published in 54 journals, 5 articles out of each journal. Responses (80%) indicate the superior quality of keywords, both as content descriptors and as retrieval tools. Author judgements on these 2 different aspects do not always converge, however. CAS's indexing policy to cover only 'new' aspects is reflected in author's judgements that index lists are somewhat incomplete, in particular in the case of thesaurus terms (index headings). The large effort expanded by CAS in maintaining and using a subject thesuaurs, in order to select valid index headings, as compared to quick and cheap keyword postings, does not lead to clear superior quality of thesaurus terms for document description nor in retrieval. Some 20% of papers were not placed in 'proper' CA main section, according to authors. As concerns the use of indexing data by third parties, in bibliometrics, users should be aware of the indexing policies behind the data, in order to prevent invalid interpretations

    Abstract
    Reports results of a bibliometric study of the authorship characteristics of articles published in 4 major information science periodicals: JASIS, Information technology and libraries, Journal of information science, and Program. The aim was to determine the details of their authors, such as: sex, occupation, affiliation, geographic distribution, and institutional affiliation. A total of 163 articles published in 1993 and written by 294 authors were analyzed. Results indicate that: men (206 or 70%) publish 3.0 times more articles than women (69 or 23,5%). Schools of library and information science contributed the most authors. The majority of authors came from the USA (148 or 50,3%), with the Midwest region claiming the largest share (110 or 25,0%). Academic libraries (110 or 37,4%) account for the major share of library publication. 12 schools of library and information science, in the USA, contributed 32 authors (50,0%) and assistant professors (25 or 39,1%) publish the most in these library schools. Male school of library and information science authors publish 1,6 times more than their female counterparts

    Abstract
    This paper considers the relevance of Charles Ami Cutter's principles of bibliographic access to the uiniverse of Internet accessible digital objects and explores new methods for applying these principles in the context of new information technologies. The paper examines the value for retrieval of collecting authors' names, identifying authors' roles, collocating works and versions, and providing subject access through classification and controlled vocabularies for digital resources available through the World Wide Web. THe authors identify emerging techniques and technologies that can be used in lieu of or as a supplement to traditional cataloging to achieve these functions in organizing access to Internet resources
