The main purpose of the present contribution is to provide practical guidance with regard to selecting a suitable data repository for research data. It might be helpful for researchers, librarians, and research support staff. Choosing a research data repository (RDR) that is appropriate for research data can be challenging and may be influenced by various factors such as the specific character of the data, requirements imposed on the researchers by third parties, e.g. a funding agency or publisher. Therefore, different types of repositories are briefly characterized in recognition of the fact that scientific disciplines or research communities have different requirements for their data management – sometimes due to the characteristics of their data, and to some extent due to the specific academic culture that has evolved. Further, directories of data repositories are presented that may be helpful in finding an appropriate place for research data storage and/or data publication. Next, data policy frameworks of some scientific journal publishers are summarized pointing to a broad spectrum of potential data sharing requirements when submitting to a journal. The final section discusses some important issues and questions to be considered in the repository selection process.
