GENERAL ARCHIVAL GUIDELINES
HABS/HAER/HALS documentation must be prepared using specific archival materials and
archival processes in order to comply with the permanence standards that govern the collection.
By adhering to these standards, even the very earliest HABS records from the 1930s are still
available for researchers and will be into the future. Non-archival material deteriorates for two
principal reasons: harmful substances in the environment attack it, and/or the physical and
chemical composition is such that it will deteriorate regardless of how it is stored.
Adhesive labels of any kind should not be used.
CD/DVDs. CD/DVDs are acceptable for short-term storage and transfer of surveys materials to
NPS. Because of the possibility of data loss, we do not recommend them for long-term storage.
CD/DVDs can be labeled with a CD/DVD pen designed for that purpose. An inkjet printable
disk that has a printable surface can also be used. No adhesive labels should be used as this
damages the disk. To prevent warping or cracking, disks should be stored in a plastic case,
commonly referred to as jewel cases.
Erasers and Corrections fluids should not be used except for Staedtler Mars® white vinyl
plastic erasers, which are considered safe and are available in most art supply stores. Most other
erasers, including pencil erasers, contain harmful chemicals like sulfur.
Food. Do not drink, eat, or smoke near documentation.
Ink - Black ink for drawings should be carbon-based rather than dye-based, waterproof, and
state that it is formulated for use on drafting film. Inks recommended by the Library of
Congress are: Koh-i-noor Rapidraw® waterproof black India; Koh-i-noor Universal®
waterproof black India; Higgins Black Magic® waterproof drawing ink; Staedtler Mars® matic
drawing ink; and Pelikan “FT” drawing ink. These inks are available from office and artists
suppliers.
Ink - Ballpoint ink contains acidic oil, which migrates and should never be used on any part of
the documentation.
Ink – Black ink for labeling negatives should be permanent, indelible, waterproof, and
designed for use on polyester film.
Laser printing on negative sleeves, photo mount cards, and Cover Sheets is not archival. Laser
printing does not permeate these materials. These materials should either be impacted printed
(e.g., typewriter) or xerographically printed (most large office copy machines print
xerographically). Laser-printed archival bond for historical reports and Index to Photographs is
acceptable.
Light is very damaging to documentation, causing fading and discoloration. Materials should
not be left where they will be exposed to sunlight or bright lamps.
Mylar® can be used for sheet sets but vellum is strongly preferred for its archival stability.
Drawings can be drawn on Mylar® archival ink. Drawings that are plotted should use vellum.
Negative sleeves must be lignin free and follow the same pH levels as archival paper. It is
preferable to have no thumb cut on the sleeve; however, a thumb cut on the seam side is
acceptable as long as it does not expose the negative. The adhesive must close the seams to
within ⅛" of the entire length of the edge. No adhesive must appear beyond the inner or outer
edge of each seam, nor on the inside of sleeves. Seams should be smooth and flat with no
