If, in the course of your research for your doctoral studies, you are consulting archival material in museums, archives or special collections, you may find that some of this material is unpublished and additionally the author may be unknown or difficult to trace (Orphan Work). In terms of copyright compliance, this raises several issues when it comes to the inclusion of substantial extracts or images in your dotoral thesis.
If you are dealing with unpublished material or orphan works, you may need to assess the risk of including the material if you are unable to obtain permission. The JISC Strategic Content Alliance (SCA) IPR Toolkit is a very useful resource for checking the exact duration of copyright in unpublished material as well as guidance and support in using orphan works.
