When it is unclear as to the copyright issues that would emerge owing to the fact that some of the interview guides and codebooks may have appeared as appendices in various published articles there are resources at hand.
During the process of building the repository use can be made of the website Sherpa RoMEO.
SHERPA RoMEO is a searchable database of publisher's policies regarding the self- archiving of journal articles on the web and in Open Access repositories. Sherpa RoMEO aggregates and analyses publisher open access policies from around the world and provides summaries of self-archiving permissions and conditions of rights given to authors on a journal-by-journal basis.
If an academic author wants to put their research articles on-line, they are faced with an increasingly complex situation. Evidence shows that citations to articles made openly accessible in this way are taken up and cited more often than research that is simply published in journals. Also some funding agencies require open access archiving for their research, to increase the use of the information generated.
However, some publishers prohibit authors from using their own articles in this way. Others allow it, but only under certain conditions, while others are quite happy for authors to show their work in this way.
Authors can be left confused: RoMEO helps to clarify the situation.
