Finding existing data for reuse

Over the past decades there has been exponential growth in the volume of data available. This growth in data availability brings opportunities to enable (cross-disciplinary) research, but also increasingly challenges finding relevant data for your research.

Nevertheless, considering reusing data could

  • Avoid duplication in generating data...
  • ... which saves time and money
  • Help in improving and/or validating research methods
  • Allows integration (e.g. meta-analysis) of data from different studies...
  • ... which opens up new avenues of research

Where to find existing data?

You can use several sources to look for data sets:

  • Research@WUR lists data sets in different repositories by Wageningen University & Research authors.
  • DataSearch lists data sets from various disciplines. It also contains supplementary data from scientific articles.
  • DataCite also lists data sets from a range of disciplines.
  • Mendeley Data list data sets from a range of disciplines and from multiple (institutional) repositories
  • OpenAIRE lists data sets and other types of research output
  • WorldWideScience lists data sets and other types of research output
  • ScholeXplorer collects links between data sets and literature. This way it enables you to find data sets underlying articles, or articles based on data sets.
  • Re3Data lets you browse data repositories rather than data sets. Once you find a suitable repository, you can look for a data set on the repository website.
  • Zanran is a service that scans the public internet for webpages that contain numerical data or statistics.
  • Reference to the data in an article
  • Supplementary files
  • Data journals
  • Colleagues with (un)published data sets
  • Personal or institutional websites
