I would like to introduce to a great blog called La Francopolyphonie.
La Francopolyphonie is a yearly peer-reviewed journal.
You can find free access to all issues and articles on this blog.
There are many, many interesting articles, some also on self-translation as for instance:
Tamara CEBAN, La problématique de l’autotraduction chez Panaït Istrati
or on self-translators like Alexakis:
Elena-Branduşa STEICIUC, Vassilis Alexakis: le passage d’une langue à l’autre
The articles are written in Romanian or French.
