A shortened version of the dissertation by Marianne Bessy on Vassilis Alexakis will be published by Rodopi next month. On the editor's homepage you can take a look at the content of the book.
It is the first book-length study of Alexakis bilingual work and I can highly recommend reading it.
I presented the dissertation about 2 years ago on another blog post. The free online version of the dissertation to which I refered in my previous post has been removed from the site.
