Thanks to a Preservation Assistance Grant from the National Endowment for the Humanities, the Mark Twain House & Museum was able to purchase 16 new data loggers for the historic  House, as well as an exterior logger, to monitor temperature and humidity via Bluetooth. Such monitoring is essential to maintain and preserve this important and historic building. Additionally, the museum was able to purchase 46 custom archival book boxes to store, and help preserve, books from its special collection. These books include those from Mark Twain’s personal library, some of which contain his marginalia; books that belonged to members of his family; and other books of significance to the author’s life and work.

During Preservation Week in April, the Curatorial Department installed the new data loggers throughout the house, which are now taking recordings of the temperature and humidity. They also rehoused rare books from the special collection into the new storage boxes.
