Oversized documents such as abstracts, maps, and charts, should be interleaved with pH balanced, buffered tissue or paper made for long term storage. Documents should be placed in map cases or flat file boxes for storing. List the contents of each box or case on the outside so that the items inside are not handled more than is necessary. Rolling or folding oversized materials should be avoided as both of these treatments can cause damage that may not be reversible. Before moving oversized documents, place them on a sturdy sheet of card stock that is larger than the item you are moving.
