The co-first and co-corresponding author phenomenon in the pharmacy and anesthesia journals

Abstract

In this poster, we describe partial findings from a larger study that explored the co-first and co-corresponding author phenomenon in two biomedical research areas, pharmacy and anesthesia. The top 10 journals in the two areas by the five-year impact factor as listed in 2013 JCR were used for the paper sources. A total of 17802 pharmacy papers and 35801 anesthesia papers were included in the analyses. Each paper was manually examined to identify the co-first and co-corresponding author papers. In this poster, we will show the distributions of the paper numbers and percentages of the co-first and co-corresponding papers over twenty years (1995–2014), the distributions of author numbers sharing the co-first and co-corresponding authorship, and the combinations and distributions of the authors' byline positions.
