Wislar JS, Flanagin A, Fontanarosa PB, et al. Honorary and ghost authorship in high impact biomedical journals: a cross sectional survey. British Medical Journal 2011;343:d6128
Ensuring appropriate authorship remains an important issue for authors, academic and research institution, and scientific journals. This study aimed at assessing the prevalence of honorary and ghost authors in six leading general medical journals in 2008 and at comparing this with the prevalence relative to 1996. Results showed that the total prevalence of articles with inappropriate authorship was 21%, a decline from 29.1 in 1996.
