New French book on Welles' legacy

[NoFake]

The homepage write-up on "Après Welles: Imitations et influences" has a very useful index of articles found in the book. Interestingly, all the titles are in English.

Does this mean that the essays themselves are in English, or have the titles been translated for Wellesnet? (The link at the end of the write-up posts to a page that suggests that they're in French.)

Thanks!
