What is a Data Access Statement and do I need one in my publication?

Some research funders such as the EPSRC require you to include Data Access Statements in your pending publications. The RCUK Policy on Open Access also states that

“All papers must include details of the funding that supported the research and, if applicable, a statement on how the underlying research materials – such as data, samples or models – can be accessed.”

These short statements explain how and where the data supporting your publication can be accessed (the mention «contact author» is not sufficient). A sample of Data Access Statements is available.

To know if your funder requires such a statement, check the list of funders’ policies on Open Access.
