The acid from the pages can damage a photo, and having photos inside can damage the spine of a book. Stack old books to store them. You want good air circulation, and closed plastic bags can also trap moisture. Seal the bag for a week. When you open it and remove the book, the bugs will be dead.
Newspapers are hard to preserve and store.
We have several old photographs that we want to share with other members of the family, but nobody has any idea what happened to the negatives. The photocopy light will actually fade the photo. Instead, take it to a photo shop, where they can make a negative without damaging the original. Instead, write on a self-adhesive label and then attach it to the outside of the plastic sleeve.
