Worldwide contributors to the literature of library and information science: top authors, 2007–2012

This study identifies the top individual contributors to 31 LIS journals from 2007 to 2012, both worldwide (all disciplines) and among four groups: LIS faculty in the US and Canada, LIS faculty in the UK, LIS faculty in other countries, and librarians worldwide. The distribution of authorship is highly skewed. Although more than 9,800 authors (86.4 %) each contributed no more than a single article over the six-year period, the top 50 authors (0.4 %) each contributed eight or more articles, with an average of 13.0. Together, the top 50 authors account for nearly 8 % of the LIS literature. Moreover, the most productive LIS faculty are concentrated in relatively few universities. Faculty in the natural sciences and LIS are more likely to be found among the top 50 authors than their overall contributions would suggest, while librarians, computer scientists and non-academic authors are underrepresented. Top authors are especially likely to publish in the Journal of Informetrics and Scientometrics. Among American LIS faculty, the list of the most prolific authors has changed substantially over time. Only three of the top 21 authors of the 1999–2004 period can be found on the current top-20 list.
