    • The real thing image

2017 marks 40 years of CCAHA. Every Friday, we'll share the articles, photos, and recollections that tell the story of how CCAHA became a world-renowned leader in conservation science.

This article highlights one of CCAHA’s early, high-profile projects: the 1984 treatment of a draft of the Declaration of Independence written in Thomas Jefferson’s hand. The article states that the draft was likely written on July 3, 1776, and “represents the Declaration as the drafting committee presented it to the Continental Congress.” Jefferson underlined the passages eventually deleted by Congress in the final version.

The article describes the draft’s treatment in one concise sentence:

To preserve the four pages of the document, the conservation center washed, deacidified, and mended the pages, repaired them with Japanese-type Kozo tissue, placed each leaf in polyester film and then between Plexiglas.
