Consult Access Deacidification database to see if the item has been designated for deacidification

 

Housing

  • Any item that meets any of the following criteria should have additional housing:
    • The spine and/or boards are detached or fragile
    • The text block has any loose gatherings or pages
    • The book is not able to support itself when stood on-end; consult Deborah or Steve G. as necessary
    • The book needs additional protection (e.g., has paper wrappers; is structurally sound but with red-rot) should have acid-free sleeve and envelope)
  • Procedures
    • If the item will fit comfortably into an acid-free sleeve and envelope, the cataloger will supply the sleeve, the reading room will supply and label the envelope
    • If the current housing is not protecting the book or is too difficult to operate, mark book for phase-box and return old housing to Steve G.
    • In the instance that a housed item is stabilized but the housing isn't optimal (such as for the 1703 Hamlet quartos which are in clam-shell boxes but should optimally be in a housing that helps lift the quartos from the box), add the item's shelf mark to Housing list on the Catalogers Mending spreadsheet (L:\Mending Trucks\CatalogersMending.xls), to be addressed at a later point by conservation (as determined by Steve G. and Renate, Feb. 2, 2011)

 

Deacidification

  • Books on the deacidification list that are in poor condition should be marked for hand-spray deacidification at Preservation Technologies
  • If uncertain whether or not to mark for hand-spray or mass deacidification, mark item for hand-spray, and Preservation Technologies will review and make a final decision (they will give extra attention to anything marked for hand-spray, but may end up able to send many of those items through the machine anyway)

 

Notation

  • Add a 583 action note, using PDA terminology if the book is identified as needing deacidification or phase-boxing. 
    • 583 1_ housed ǂd {YYYYMMDD} ǂx {your initials} ǂ2 pda ǂ5 DFo
    • 583 1_ mass deacidified ǂd {YYYYMMDD} ǂx {your initials} ǂ2 pda ǂ5 DFo (Note: Use this formulation even for books marked for hand spray)

 

  • For bibliographical records with multiple items, including multi-part monographs or multiple copies, add a ǂ3 at the beginning of the 583 field to specify which items are receiving which treatment:
    • 583 1_ ǂ3 v.1,v.4,v.6 ǂa housed ǂd 20100708 ǂx EGB. ǂ2 pda ǂ5 DFo
    • 583 1_ ǂ3 copy 2 v.1-10,13,15 ǂa housed ǂd 20100518 ǂx EGB ǂ2 pda ǂ5 DFo 
    • 583 1_ ǂ3 copy 2 v.11,12,14 ǂa mass deacidified ǂd 20100518 ǂx EGB ǂ2 pda ǂ5 DFo

 

Return from deacidification

  • Technicians at Preservation Technologies will mark the conservation flags; flags for those marked as hand-sprayed will be given to the catalogers, who will update the 583 fields
    • 583 1_ conserved ǂd {YYYYMMDD} ǂx deacidified ǂx {your initials} ǂ2 pda ǂ5 DFo
    • 583 1_ ǂ3 copy 2 v.1-10,13,15 ǂa conserved ǂd 20100518 ǂx deacidified ǂx EGB ǂ2 pda ǂ5 DFo

 

Finalization

  • Remove to the curatorial file any items tipped into a book headed for deacidification, and leave a note in the 852 ǂz
  • If there are folded materials bound-in, such as playbills, book should be marked for hand-spray deacidification, and conservators can make ultimate decision to send for mass deacid. (per conversation with S.G. 18 Nov 2010)
  • Insert acid-free flag(s) designating deacidification and/or phase-boxing into every item designated for treatment
    • For those volumes needing both hand-spray deacidification and phase boxing, mark both bubbles
    • Initial and date-stamp each flag, and be sure to write the call number of the item in the space at the top
