Simply put, acid and lignin cause paper to deteriorate. A good example of this is newspaper. You will notice that after only a couple of days, newspaper begins to turn yellow and brittle. The same will happen to your scrapbook and photographs over time if the proper materials are not used. These materials do not only include paper? adhesives, pens, markers, stickers, and anything else that comes into contact with your photographs must be acid and lignin free.
