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?The ethics of authorship is well-researched in the health sciences, but it has got less attention from social scientists [1]. In higher education and research institutions, authorship credit is considered academic currency [2,3]. Several organizations, especially the publishers of scientific articles, provide guidelines on authorship credit. For instance, in health sciences and its related disciplines, the International Committee of Medical Journal Editors (ICMJE) 1 has published the authorship criteria (see Table 1) as a part of Vancouver protocol. Vancouver protocol includes the guidelines and recommendations for conducting, reporting, editing, and publication of scholarly work in medical journals. The influence of ICMJE criteria is expanding to other disciplines as well [4]. The authorship refers to two essential aspects that the research team needs to decide about, 1) Who should be included as an author? (Authorship Naming), 2) Who would be listed as the first author, and what would be the subsequent positions of co-authors? (Authorship order). Authorship guidelines suggest that a substantial contributor would be listed as an author. However, in which order, the authors' names should be displayed, guidelines are silent in this regard [5,6]. Other contributors who do not meet authorship criteria, their names should have to be listed in the acknowledgment section [4].The guidelines on who should be an author differ from one organization to another, and the difference could be within the same research discipline. These differences could be confusing for the authors and ultimately could lead to poor authorship decisions [7]. The existing authorship criteria provide a road-map about authorship naming, but it is hard to find such guidelines regarding authorship order [8]. Although almost every scientific article publisher provides authorship criteria, researchers reported disagreements and unethical practices regarding authorship, for instance, giving authorship to undeserving persons or ignoring substantial contributors [9]. There is a need to increase awareness about the ethics of authorship and open up a dialog among the institutions and researchers [10].This study aims at investigating the practices and issues related to the ethics of authorship. A review of empirical articles/papers published between 2014 to 2020 has been conducted. The selection of the primary studies was made based on the criteria that the presented study ...
