I usually scan newspaper articles and then print on good paper. If you really want to use the article, there are sprays to de-acidify them. You can also place the article in a clear bag or something to protect surrounding photos.
I have done a ton of these. I finally found (on here someplace) someone that did them. They gave me the idea of using Contact paper. It works AWESOME!! It's in rolls and you want to get the clear. This paper is normally used to put down inside your cupboards. I have used so much I need to take stock on it Let me know if you have further questions I know quite a bit about it. Good luck. By the way PM me it's easier to respond.
