Only a few things.

* **title:** The title field would be left empty in MLZ, but I think leaving those details in there will be okay; they will just be ignored when generating citations. It might affect duplicates detection, though, since that relies on title matching where more precise identifiers are not available.
* **shortTitle:** This should be only "Deux Ex" in this instance.

Everything else looks okay. What does "Beschl." mean? Is it used in citations?
