blogis librorum. A blog about books. Rare books.

As every collector of rare books and documents knows, one of the biggest barriers to collecting is preservation. The effect of time, dust, light, and moisture in the environment on paper and parchment can often lead to discoloration and degradation. Care must be taken to protect delicate books and documents from being slowly destroyed by age and the elements.

This is no different for historical documents, whose caretakers endure great pains to preserve history's most important works. In the case of the Constitution of the United States, the National Archive enlisted an unlikely source to help preserve one of America's most notable documents: NASA.

The 16^th century was a period of massive change within the printing world as new inventions and methods revolutionized how people read.
