Scientific publication is one of the main channels for disseminating research results and one of the most important means of determining the presence of women in scientific research. This article aims to conduct a bibliometric analysis in the Library and Information Science (LIS) field, from a gender perspective, by analysing Journal of Information Science (2015–2020). To reach this goal, the research has been developed in several stages (data collection, gender authors’ identification, validation of authorities, contact by email and analysis of results) to identify 326 contributions and 697 authors finally. Analysis patterns showed outcomes on gender (single and multiple authors), scientific collaboration, authorship time-course, authorship productivity as well as institutional and geographic affiliation. Some conclusions show that male and female authors are not equally represented in the journal, with a great difference in the case of collective authorship. Overall, there is a clear trend of single and multiple male authorship.
