What is Iron Gall Ink

This chapter describes changes in conservation practices in the twenty-first century. As public spaces were repurposed from storage to study and work space, collections were moved into dedicated spaces that could sustain tighter environmental controls than an open stack environment. Digital access relieved pressure on print collections in many libraries, while digitization projects required intervention by conservators. Rehousing replaced repair as a default preservation strategy for many materials, and improved housing materials played an increasingly important role in conservation. In this chapter, conservation for disaster recovery is examined from the perspective of short-term in situ response techniques, and longer term laboratory treatments to restore access to affected collections. Surveys have suggested that routine practices have evolved slowly since 2000. With an emphasis on novel and unique techniques in the peer-reviewed literature, many important questions about routine conservation procedures in disaster recovery have remained unanswered.
