If there is any doubt about proper treatment or housing, consult with the Preservation Coordination Librarian about what treatment or housing may be required. Pull item(s) needing conservation or custom housing. Flag the folder or original location of the item with a “Manuscript Item(s) Temporarily Removed” flag. Complete Preservation Request slip. Use one for each unit of storage (usually folder, sometimes box). Use the final call number (not accession number or uncat number) on the slip. If indicating that item can go from treatment to the shelf, provide barcode and label if the item is not already housed, barcoded, and labeled. Route item(s) and completed Treatment Request Slip(s) to the Preservation Assistant. ‹ 6.3 Routing Instructions for Preservation Treatment up 6.3.2 When Items Are Returned After Treatment ›
