Abstract

We investigate the contributions of particular disciplines, countries, and academic departments to the literature of library and information science (LIS) using data for the articles published in 31 journals from 2007 to 2012. In particular, we examine the contributions of authors outside the United States, the United Kingdom, and Canada; faculty in departments other than LIS; and practicing librarians. Worldwide, faculty in LIS departments account for 31% of the journal literature; librarians, 23%; computer science faculty, 10%; and management faculty, 10%. The top contributing nations are the United States, the United Kingdom, Spain, China, Canada, and Taiwan. Within the United States and the United Kingdom, the current productivity of LIS departments is correlated with past productivity and with other measures of reputation and performance. More generally, the distribution of contributions is highly skewed. In the United States, five departments account for 27% of the articles contributed by LIS faculty; in the United Kingdom, four departments account for nearly two-thirds of the articles. This skewed distribution reinforces the possibility that high-status departments may gain a permanent advantage in the competition for students, faculty, journal space, and research funding. At the same time, concentrations of research-active faculty in particular departments may generate beneficial spillover effects.

Abstract

We investigate the extent to which open-access (OA) journals and articles in biology, computer science, economics, history, medicine, and psychology are indexed in each of 11 bibliographic databases. We also look for variations in index coverage by journal subject, journal size, publisher type, publisher size, date of first OA issue, region of publication, language of publication, publication fee, and citation impact factor. Two databases, Biological Abstracts and PubMed, provide very good coverage of the OA journal literature, indexing 60 to 63% of all OA articles in their disciplines. Five databases provide moderately good coverage (22-41%), and four provide relatively poor coverage (0-12%). OA articles in biology journals, English-only journals, high-impact journals, and journals that charge publication fees of $1,000 or more are especially likely to be indexed. Conversely, articles from OA publishers in Africa, Asia, or Central/South America are especially unlikely to be indexed. Four of the 11 databases index commercially published articles at a substantially higher rate than articles published by universities, scholarly societies, nonprofit publishers, or governments. Finally, three databases-EBSCO Academic Search Complete, ProQuest Research Library, and Wilson OmniFile-provide less comprehensive coverage of OA articles than of articles in comparable subscription journals.
