If you are enclosing a sheet of paper with notes along with the document in the sheet protector, make sure the notes are on an acid-free paper stock too. Make note that most computer printer paper you purchase at the office supply store is not archival quality material. The preservation of old newspaper clippings can be difficult. There are several reasons for this. Most important, modern newsprint paper stock was never intended for archival usage.
Modern newsprint tends to disintegrate quickly.
It was actually disintegrating. Add moisture and you have a recipe for extremely rapid deterioration. Make Copies Immediately Photocopying newspaper clippings admittedly exposes them to a dose of bright light, and light is an enemy of newsprint. However, if you are interested in preserving the content of a newspaper article or clipping, there can be no substitute for a one-time exposure when the clipping is new. Once done, you will then have a backup copy on a more stable type of paper.
