  Authorship ethics is a central topic of discussion in research ethics fora.
There are various guidelines for authorship (i.e., naming and order). It is not
easy to decide the authorship in the presence of varying authorship guidelines.
This paper gives an overview of research on authorship practices and issues. It
presents a review of 16 empirical research papers published between 2014 --
2020. The objective is to learn how various research disciplines handle
authorship. What are the authorship practices in various research disciplines,
and what are the issues associated with these practices?
