Déjà vue database finally

There is a new database that describes itself as

a database of extremely similar Medline citations. Many, but not all, of which contain instances of duplicate publication and potential plagiarism. Deja vu is a dynamic resource for the community, with manual curation ongoing continuously, and we welcome input and comments.

As far as I can see, this is not so much self-plagiarism but self-repetition, yea, yea.
