You buy a box of wallpaper adhesive, or some people have had success with liquid starch, if you want to remove it easily. Mix up about a quart of paste at a time, dip the pages and apply smoothing with your hands. Newspapers might be a bit tricky as the are so thin, but if you dip quickly and remove excess by running it through your fingers, you should be able to create a nice affect. Remember that smaller pieces, if you are overlapping will look and react best. Also, the straight edges of pages might detract if you are going for a random look, be sure to tear the edges of the pages. Use only straight lines at the corners, top and bottom to reduce the need for trimming.
