Having discussed such proposals in the past, currently JAR does not accept proposals for special or thematic issues. We consider that although a research project may seem to suit a thematic issue, publishing research in relation to a specific theme is often problematic, suggesting a narrow scope of interpretation. In addition to this, the cost of producing additional issues was too high for many who were interested.
For those interested in special issues, you may want to consider approaching Ruukku. Studies in Artistic Research and VIS. Nordic Journal for Artistic Research two of the other journals that engage with the rich-media capabilities of the Research Catalogue.
