It is a way to treat a large number of materials fairly quickly providing them with a stable environment. For this set of Eugène Séguy prints form the Joseph F.

The welder is particularly useful for encapsulating brittle, fragile items ensuring that information is preserved while allowing them to be handled. Bill disassembled the motor unit, cleaned and oiled the machine and replaced several more »

April 21-27 is Preservation Week! In honor of this event, we will be featuring preservation-related content on the Smithsonian Libraries’ blog as well as our other social media outlets, like Facebook, Twitter and Tumblr. Today, we offer you a peek inside our own Book Conservation Lab! The Preservation Services Division of the Smithsonian Libraries is committed to the preservation, safe exhibition, and long-term access to collections objects, many of which are irreplaceable. The primary mission of the Book Conservation Lab (BCL) is to treat special and general collections items needed for research, exhibition or digitization.
