Instructions
Inspect your newspaper to determine whether it is printed on rag linen or wood pulp, which is high in acid content. Most newspapers printed before 1876 were printed on rag linen, and if yours is, too, you can disregard the instructions that apply to controlling acid content.
De-acidify high-value newspapers printed on wood pulp. This can be done professionally by an archivist or conservator, or you can purchase an aerosol spray and do the job yourself.
Scan or photocopy the entire newspaper, or parts that are important to you. This will allow you to refer to information in the newspaper without having to refer to the original each time. When photocopying, use acid-free paper if possible.
Unfold the newspaper completely and wrap each piece in acid-free paper.
Seal the acid-free paper in a few spots with archival tape. Leave some spots untaped to allow air to flow in and out.
Store the newspaper in a box no larger than 10 inches deep.
Store the box in a dry, heated (but not humid) area such as under a bed or in a cupboard. Storing it in an attic or basement can leave your paper vulnerable to mold, bugs and mildew.
