In order to extend the useful life expectancy of significant historical records, the City Archives devotes extra resources to clean, de-acidify, repair and protect invaluable City maps and records.  This process often includes protective Mylar enclosures for each page to prevent soiling and ordinary wear and tear.  In addition, each record is microfilmed and/or digitized to improve public access.

Lastly, dependent where the element was stored and the overall aging byproduct, records will typically have tears and/or ripped breaks.  These are then supported with Japanese paper and a wheat starch paste, carefully lined with supplemental Japanese paper adhered to the element with an additional wheat starch paste that proves to remedy the aging process and disintegration.
