The objective of this study is to explore the prevalence and characteristics of data sharing policies in library and information science (LIS) journals, focusing on their relationship with journal metrics, publisher volume (number of journals managed by the publisher), and open access (OA) status. The study examined the link between data sharing policies and journal metrics in LIS journals indexed in Scopus. Using secondary data from the SJR portal and qualitative data from author guidelines, the study revealed several key findings: First, a positive relationship existed between publisher volume and the presence of data sharing policies, with high-volume publishers consistently implementing such policies. Second, 50.2% of LIS journals lacked data sharing guidelines, indicating a significant gap. Third, journals that encouraged or required data sharing under certain conditions tended to perform better in metrics such as quartiles, h-index, and citation impact. Fourth, data sharing policies were more common in higher-ranked journals and were linked to better journal metrics. Fifth, higher-ranked journals were more likely to include details on data statements, DOIs, and repositories than lower-ranked journals. Lastly, non-OA journals were more likely to encourage practices such as including data repositories and supplementary files in submissions, compared to OA journals, revealing unexpected disparities. In conclusion, data sharing policies in LIS journals showed associations with journal ranking and publisher volume, with non-OA journals showing higher presence of certain data sharing practices.
