Citation indicators are increasingly used in book-based disciplines to support peer review in the evaluation of authors and to gauge the prestige of publishers. However, because global citation databases seem to offer weak coverage of books outside the West, it is not clear whether the influence of non-Western books can be assessed with citations. To investigate this, citations were extracted from Google Books and Google Scholar to 1,357 arts, humanities and social sciences (AHSS) books published by 5 university presses during 1961-2012 in 1 non-Western nation, Malaysia. A significant minority of the books (23% in Google Books and 37% in Google Scholar, 45% in total) had been cited, with a higher proportion cited if they were older or in English. The combination of Google Books and Google Scholar is therefore recommended, with some provisos, for non-Western countries seeking to differentiate between books with some impact and books with no impact, to identify the highly-cited works or to develop an indicator of academic publisher prestige. © 2014 ASIS&T.

This stated preference study approached the issue on sub-categorization of the information science–library science (IS–LS) journals listed in the Journal Citation Report (JCR) 2011. To investigate this, 243 active authors/editors publishing in this field were requested to indicate their preferred category to 83 journal titles listed in JCR 2011 from four options: information science (IS), library science (LS), information systems (ISys) and do not know/undecided. Based on the popularity count, respondents assigned 39 titles to LS, 23 titles to IS and 21 titles to ISys. Twenty-five titles received high “do-not-know” counts—these are titles in non-English languages, information management and publishing sub-fields. Only one title in LS was grouped in the highest quartile by impact factor, compared to 8 titles in IS and 11 in ISys. This indicates that LS journals are hardly represented among the top 25 % of the impact factor distribution of JCR’s ranked IS–LS journals. Respondents show concern about the “fit” of information systems journals in the IS–LS category. © 2014, Akadémiai Kiadó, Budapest, Hungary. Source

The study compares the coverage, ranking, impact and subject categorization of Library and Information Science journals, specifically, 79 titles based on data from Web of Science (WoS) and 128 titles from Scopus. Comparisons were made based on prestige factor scores reported in 2010 Journal Citation Reports and SCImago Journal Rank 2010 and noting the change in ranking when the differences are calculated. The rank normalized impact factor and the Library of Congress Classification System were used to compare impact rankings and subject categorization. There was high degree of similarity in rank normalized impact factor of titles in both WoS and Scopus databases. The searches found 162 journals, with 45 journals appearing in both databases. The rankings obtained for normalized impact scores confirm higher impact scores for titles covered in Scopus because of its larger coverage of titles. There was mismatch of subject categorization among 34 journal titles in both databases and 22 of the titles were not classified under Z subject headings in the Library of Congress catalogue. The results revealed the changes in journal title rankings when normalized, and the categorization of some journal titles in these databases might be incorrect. © 2012 Akadémiai Kiadó, Budapest, Hungary.
