<P>Research organisations and cultural heritage institutions could in certain cases, for example for subsequent verification of scientific research results, need to retain copies made under the exception for the purposes of carrying out text and data mining. In such cases, the copies should be stored in a secure environment. Member States should be free to decide, at national level and after discussions with relevant stakeholders, on further specific arrangements for retaining the copies, including the ability to appoint trusted bodies for the purpose of storing such copies. In order not to unduly restrict the application of the exception, such arrangements should be proportionate and limited to what is needed for retaining the copies in a safe manner and preventing unauthorised use. Uses for the purpose of scientific research, other than text and data mining, such as scientific peer review and joint research, should remain covered, where applicable, by the exception or limitation provided for in Article 5(3)(a) of Directive 2001/29/EC.</P>
