Data Collection

Access to existing Datasets

It is not always necessary to collect new data for your research. More and more research data is made openly available for further research and analysis in archives or data depositories. Re-using existing datasets can save a lot of time and money. We therefore recommend you to check which datasets are already available within your research field first.

Sources for existing datasets

Please let us know if you have any additional Data Archives, so we can add them to this overview.

Terms of use

Each data archive or depository has its own terms of use, but generally the most important aspects that should be taken into account when re-using an existing dataset are:

  • The acquired dataset is for personal use only and may not be distributed further
  • Always include an acknowledgement of sources (a bibliographic reference of the dataset)
  • Inform the archive or depository of the new publications that resulted from the dataset
