    Abstract
    Philadelphia, PA USA-London UK-Princeton, NJ February, 25, 2004 - Today, Thomson ISI and NEC Laboratories America (NEC) announced their collaboration to create a comprehensive, multidisciplinary citation index for Web-based scholarly resources. The new Web Citation Index(tm) will combine a suite of technologies developed by NEC, including "autonomous citation indexing" tools from NEC's CiteSeer environment, with the capabilities underlying ISI Web of KnowledgeSM. Thomson ISI editors will carefully monitor the quality of this new resource to ensure all indexed material meets the Thomson ISI high-quality standards. During 2004, Thomson ISI and NEC will operate a pilot of the new resource to receive feedback from the scientific and scholarly community. Full access to the index is projected for early 2005. When fully operational, the new resource will be a unique content collection within ISI Web of Knowledge. It will complement the Thomson ISI Web of Science(r), and provide researchers with a new gateway to discovery 4/3 using citation relationships among Web-based documents, such as pre-prints, proceedings, and "open access" research publications.

    Abstract
    Ahlgren, Jarneving, and. Rousseau review accepted procedures for author co-citation analysis first pointing out that since in the raw data matrix the row and column values are identical i,e, the co-citation count of two authors, there is no clear choice for diagonal values. They suggest the number of times an author has been co-cited with himself excluding self citation rather than the common treatment as zeros or as missing values. When the matrix is converted to a similarity matrix the normal procedure is to create a matrix of Pearson's r coefficients between data vectors. Ranking by r and by co-citation frequency and by intuition can easily yield three different orders. It would seem necessary that the adding of zeros to the matrix will not affect the value or the relative order of similarity measures but it is shown that this is not the case with Pearson's r. Using 913 bibliographic descriptions form the Web of Science of articles form JASIS and Scientometrics, authors names were extracted, edited and 12 information retrieval authors and 12 bibliometric authors each from the top 100 most cited were selected. Co-citation and r value (diagonal elements treated as missing) matrices were constructed, and then reconstructed in expanded form. Adding zeros can both change the r value and the ordering of the authors based upon that value. A chi-squared distance measure would not violate these requirements, nor would the cosine coefficient. It is also argued that co-citation data is ordinal data since there is no assurance of an absolute zero number of co-citations, and thus Pearson is not appropriate. The number of ties in co-citation data make the use of the Spearman rank order coefficient problematic.

    Abstract
    Purpose Literature practices represent the process leading up to the citation of a source, and consist of the selection, reading and citing of sources. The purpose of this paper is to explore possible factors that might influence researchers during this process and discover possible consequences of researchers' citation behaviours. Design/methodology/approach In this exploratory study, various factors which could influence literature practices were explored via a questionnaire amongst 112 researchers. Participants were first authors of articles published in 2016 in one of five different journals within the disciplines of experimental psychology, educational sciences and social psychology. Academic positions of the participants ranged from PhD student to full professor. Findings Frequencies and percentages showed that researchers seemed to be influenced in their literature practices by various factors, such as editors suggesting articles and motivation to cite. Additionally, a high percentage of researchers reported taking shortcuts when citing articles (e.g. using secondary citations and reading selectively). Logistic regression did not reveal a clear relationship between academic work experience and research practices. Practical implications Seeing that researchers seem to be influenced by a variety of factors in their literature practices, the scientific community might benefit from better citation practices and guidelines in order to provide more structure to the process of literature practices. Originality/value This paper provides first insights into researchers' literature practices. Possible reasons for problems with citation accuracy and replicating research findings are highlighted. Opportunities for further research on the topic of citation behaviours are presented.

    Abstract
    In this article a quantitative study is reported on the resistance that scientists may encounter when they do innovative work or when they attempt to publish articles that later become highly cited. A set of 205 commentaries by authors of some of the most-cited papers of all times have been examined in order to identify those articles whose authors encountered difficulty in getting his or her work published. There are 22 commentaries (10,7%) in which authors mention some difficulty or resistance in doing or publishing the research reported in the article. Three of the articles which had problems in being published are the most cited from their respective journals. According the authors' commentaries, although sometimes referees' negative evaluations can help improve the articles, in other instances referees and editors wrongly rejected the highly cited articles

    Abstract
    In spite of numerous studies of citation behaviour and the wide recognition by journal editors of the need to acknowledge intellectual debts, authors and referees need explicit reminders as to when formal refrences or acknowledgements are appropriate. Notes a 3 year experiment involving graduate students which demonstrated the varying perceptions of the need for documentation off terminology, ideas and methods. Suggests a tentative tutorial for journal editors that should be modified in each scholarly context
