Are articles in library and information science (LIS) journals primarily contributed to by LIS authors
This study measured the proportion of articles by authors affiliated with library and information science (LIS)-related institutions and proportion of LIS authors in each journal using 3224 articles published in 75 journals in 2015 in the category of information science and library science as assigned by journal citation reports (JCR). Only 33.3% of journals published over half of their articles by LIS authors. Over half of authors affiliated with LIS institutions were identified in only 30.7% of journals. Library science-oriented journals had higher percentages of LIS authors and articles by LIS authors, followed by information science-oriented journals. Not all typical LIS journals were primarily contributed to by LIS authors. Additionally, 30 journals with a weak association to LIS research substantially explained the findings and tended to have higher impact factors. Lower ranks of typical LIS journals affect research rewards for LIS researchers when JCR impact factors are emphasized.
