Answer: In some cases
Explanation: It is possible to do this, but not recommended. If you want to do it, you must make sure the underlying paper is all laying flat before you paper over it. You can get some special adhesive for this, and a small roller, to press the seam down and squeeze out the extra paste, then wipe it off. The more layers of paper there are, the harder it is to get all of it off if you want to paint it later. Painting over paper is really bad, because you can't easily get through the paint layer to steam off the paper.

Explanation: While it is always best to remove the existing wallpaper before installing new, it is sometimes possible to paper over the old installation.
