I was just wondering if any of the following mangas were still being made:

Black Cat- I've got up to chapter 133 downloaded. I've searched some other sites but I can't get any information.

Pretty Face- I've heard that this was discontinued after chapter 52 but I just want to confirm it.

Elfen Lied- I haven't seen any site that had this past chapter 23. I know this was made into an anime, but I'm certain that this was finished. Is it available for download anywhere?
