Purpose – The purpose of this paper is to study and analyse the authorship pattern, degree of collaboration, prepare list of prolific authors and test Lotka’s law of scientific productivity in spacecraft technology research. Design/methodology/approach – Data are collected from the print versions of three journals in the field of spacecraft technology for the period 2001-2011. In all 154 volumes containing 1,907 papers have been analysed, and data are presented in different table headings. Findings – Study reveals that 4,355 authors have contributed 1,907 papers. Journal of Spacecraft and Rockets has published maximum (1,487) number of papers during the study period. Multi-authored papers with 87.15 per cent of contributions have dominated this field of research. Journal of Spacecraft Technology has recorded highest degree of collaboration of 0.90. James M. Longuski has published 20 papers in Journal of Spacecraft and Rockets during the period 2001-2011. Lotka’s law of scientific productivity is tested and conforms only partially. Research limitations/implications – Study is restricted only for the period 2001-2011, and the data are collected from the print versions of three journals in the field of spacecraft technology research. Originality/value – As far as space science and technology is concerned, there are not many bibliometric studies reported in the published literature. The present study will add value to the bibliometrics literature and provide publishing trends in spacecraft technology research. [ABSTRACT FROM AUTHOR]

Purpose ? The present paper aims at analyzing the research output performance of library and information science (LIS) professionals. Citation analysis of all the journal articles published in the Collection Building journal during 2009-2012 is carried out. Design/methodology/approach ? The data for this study were drawn from a selective sample of a free e-journal, i.e. Collection Building, available through the Kuvempu University Web site without subscription or registration. A total of 91 articles published during 2009 to 2012 with 1,302 citations. The analysis cover mainly the number of articles, authorship pattern, subject-wise distribution of articles, average number of references per articles, forms of documents cited, rank list of journals, Bradford?s law. Findings ? The study reveals that journals (53.84 per cent of citations) are the most preferred sources of information used by the researchers in the field of LIS. It is followed by Web resources with 24.27 per cent, these two together constitute 78.11 per cent of total citations and remaining 21.89 per cent of citations from books, proceedings, theses, reports and gazetteer. Collection Building (USA) has ranked first with 68 (9.70 per cent) citations. Further, Bradford?s law of scattering was applied. It is observed that major citations are from journal literature. In addition, more cited materials were contributed by multi-authors, and degree of collaboration is 0.44. Research limitations/implications ? The paper presents a sense of the importance of LIS research, and as such, informs the community and researchers involved in the citation analysis. Originality/value ? The outcome of the study is an original research work with citation analysis of LIS publications. The study highlights the information materials available and used by researchers in the field of LIS, and those that need to be added for a healthy collection. [ABSTRACT FROM AUTHOR]

Purpose – The purpose of the study is to explore the publication trends of the scholarly journal Library Management, and highlight its various important aspects. Design/methodology/approach – The paper presents results of bibliometric analysis of 336 articles which were published during the period 2006-2012, in the Library Management journal of Emerald. Findings – The results indicate that the majority of the contributions by single authors and most cited documents are journal articles. The study highlights the chronological distribution of articles, authorship pattern, geographical distribution of authors, institutions wise distribution, citation pattern and length of articles. Originality/value – As yet there have been no such studies conducted that investigate the various aspects of Library Management journal. It evaluates the publication trends of the journal and has important implications for scholars and researchers. [ABSTRACT FROM AUTHOR]

Purpose – The purpose of this paper is to determine the materials cited in doctoral theses of botany, submitted to the Kuvempu University during the years 2000-2006, with the aim of improving the existing collection development of the library. Design/methodology/approach – The study employed descriptive research design. Theses submitted for the award of Doctoral degree from 2000 to 2006 to the Department of Botany, Kuvempu University were examined. The population of the study was all the theses submitted during the periods under study. Data were extracted from title page and references given at the end of each chapter. Extracted data were analysed using statistics. Findings – The study reveals that journals are the most preferred sources of information used by the researchers in the field of botany, accounting for 74.77 per cent of total citations, although citations from books, proceedings, theses, reports and patents are also found. It is also observed those researchers are not taking much advantage of internet resources. The journal Plant Cell, Tissue and Organ Culture (USA) was ranked the first, with 158 citations, accounting for 7.57 per cent of the total journal citations. Further, Bradford's law of scattering was applied. It is observed that major citations come from journal literature. In addition, more cited materials were contributed by multi authors and degree of collaboration is 0.75. Research limitations/implications – The paper presents a sense of the importance of botany research, and as such informs that community, as well as researchers involved in citation analysis. Originality/value – The outcome of the study is an original research work with citation analysis of doctoral theses in botany. It highlights the information materials available and used by researchers of the Botany Department for their research work and those which need to be added for a healthy collection.
