Frequently Asked Questions: Preservation

Supportive protective enclosures include: acid- and lignin-free folders, four-flap folders, document "preservation binders," envelopes, and document boxes (all available alkaline buffered or neutral pH); and polyester film sleeves that are stiff enough to adequately support the comic book within. Alkaline buffered storage materials provide a desirable neutralizing effect on acids in paper, but be aware that some inks may be sensitive to alkaline pH. Polyester film has the benefit of being clear, but does not contain an alkaline buffer and with little friction readily produces an electrostatic charge that can lift paper crumbs from embrittled comic books.

The Northeast Document Conservation Center has put together very useful technical leaflets on storage enclosures for small books as well as a list for Conservation/Preservation Supplies and Equipment — Archival Supplies. See additional lists of preservation suppliers.
