PRESERVATION SUPPLY CATALOG

The following is based on the 2019 Library of Congress Preservation Supply Catalog and is being adapted to the wiki format. This is a draft/sandbox page.

To Be Done

• LETS PAUSE ON THIS WORK AND FOCUS ON THE ABOVE TASKS UNTIL WE TOUCH BASE WITH ANDREW--Kkelly (talk) 16:38, 31 October 2022 (UTC)
• standardize appearance of inches and fractions, same as above.
• remove all "call Ashley's, talk to your supply coordinator, etc." CHECKITY CHECK
• standardize the use of “‘s for inches
• standardize fractions (some look weird) LET'S TALK ABOUT THIS
• I got rid of "See Photographic Negative Storage Box with Lid (# 300-342) on page 21" because that doesn't exist on page 21, or anywhere else in the catalog, that I can tell (under photographic negatives storage box without lid section).
• Microfilm Box, Reel Storage refers to left and right images. These images are currently one on top of the other.
• Should we get rid of "The catalog only lists standard LC designs and sizes" in each section? It's pretty redundant.
• I've been adding info to tables and would like to talk to you about it - not super happy with it but also not super happy with the other options.

Introduction

Preservation Supplies Program (PSP)

The Preservation Supplies Program (PSP) is an important component in the Preservation Directorate's initiative to offer comprehensive services to the various custodial and processing units of the Library of Congress. The PSP is a collaborative effort involving both the Preservation Directorate and these units that have custody of, and work with, Library collections. During the annual preservation selection process, Preservation Directorate staff work with staff from these units to select housing supplies that will be needed in the upcoming fiscal year, organize the procurement of these supplies, upon receipt of the supplies test them to ensure they pass LC specifications, and then arrange delivery of these supplies to those that requested them.

The PS Catalog

The purpose of the PS Catalog is to assist Divisions in selecting commonly used products for housing their collections. The Catalog is divided into five sections according to material: Paper Stock, Card Stock, Board Stock, Polyester, and Corrugated Board Stock. Each section illustrates the preservation supplies that the Directorate recommends for Library collection items. Information is given on possible uses and commonly used or standard sizes of the listed products. Each of the products has a Library of Congress preservation specification which accompanies the item in order to guarantee the durability, construction and appropriate qualities required for long-term storage. The specifications are located on the Preservation Directorate website: http://www.loc.gov/preservation/resources/specifications/index.html

Since many items are similar, careful reading of the product description is essential to selecting the right item for your needs. Every supply listed in the catalog has a LC Catalog number that is used to identify a specific item [Example: P100-0110]. Important variations that must be specified include such things as thickness of card stock or polyester film to be used for folders; drop front on the "long" side or the "short" side of drop-front boxes; grain direction parallel or perpendicular to the fold in card stock folders.

Not every available item is listed in the supply catalog – only those standard items which are most frequently ordered.

Frequently Asked Questions (FAQs)

Why do we have specifications that require laboratory testing before products can be accepted for use?

Many products on the market appear to be suitable, but will not last or will adversely affect the materials stored in contact with them. The LC Specifications guarantee the permanent and durable qualities and construction that are necessary for long-term storage. Certain specifications require that products which come in contact with photographic materials must pass the Photographic Activity Test (PAT). Current specifications will be updated and new specifications for other products will be written as the need arises. The specifications are located on the Preservation Directorate website: http://www.loc.gov/preservation/resources/specifications/index.html

Can we use the vendor catalogs?

The PS Catalog contains only commonly used products. Vendor catalogs or websites are an important source for new products, unusual products and ones not in the PS Catalog.

How often will the PS Catalog be updated?

The catalog will be scheduled to be updated as needed or on a yearly basis. The catalog only lists standard LC designs and sizes.

Always wear white cotton gloves when handling film images.
Should your negative and/or positive images on film be protected by a polyester or polypropylene sleeve prior to being placed in a paper enclosure? All film on acetate base should not be stored in plastic enclosures prior to paper enclosures. B/W film on a polyester base and all color film, when handled by researchers, need to be protected by polyester or polypropylene sleeves. All color film, positive and negative, stored in cold storage, ideally should be protected by polyester or polypropylene sleeves prior to paper enclosures. See note below and following pages for more information.
When placing film images into paper enclosures, the emulsion side should be away from the seamed side of the envelope if no plastic sleeve is used.

Custom-made lidded box or Metal filing cabinet

Note: Cellulose nitrate film is unstable and highly flammable. Acetate film (also known as “Safety” film) is also unstable, but is not flammable. It must be monitored and should not be stored in plastic enclosures or sealed containers. Polyester film (only available since mid 1950's) is stable. Color Dyes are unstable and will fade unless stored in cold storage. Silver images are sensitive to contaminants in the air and from enclosures. Therefore, Preservation tests housing supplies to be used with photographs to ensure they pass the Photographic Activity Test (PAT) and other ISO standards for Photograph enclosures.

Issues to be Considered for Photographic Materials

Use of polyester or polypropylene sleeves inside paper enclosures

Do Not Use Plastic Sleeves:

When film base is acetate or nitrate:

• All acetate film is unstable and degrades in normal (70 degrees/50% RH) environmental conditions. It should not be stored in plastic enclosures, unless temporarily, when handled by staff or researchers. Always place directly into paper enclosures.

When a flaking or friable film image needs housing:

• Place directly into a paper enclosure.

Do Use Plastic Sleeves:

For protection from abrasion and scratching during handling:

• Before being handled by staff or researchers, B&W film and all color film need to be protected by plastic sleeves to reduce likelihood of abrasion and scratching.

For protection from scratching due to abrasion from the surface texture of the paper enclosure:

• All film surfaces can be scratched. This is a concern for highly valuable, highly vulnerable, highly used film images. The plastic sleeves protect the film surface and prevent moisture build-up on the surface of the film in cold storage during changing climate conditions. The use of plastic sleeves inside paper enclosures is necessary when transporting film images to and from cold storage vaults or in the case of humidity elevation in the vault.

Cool and Cold Storage

Cool and cold storage slows the deterioration of unstable photographic materials, especially cellulose nitrate, cellulose acetate and color dyes. Cool storage will slow all forms of photographic deterioration, especially film base deterioration (acetate, nitrate), and color dye deterioration. Cold storage slows deterioration more, especially for color dye images. Cool storage is useful for B&W acetate film in order to slow acetate deterioration. If B&W film is used frequently, the cool storage is preferable since the warm-up time to room temperature is less than for items stored at cold temperatures. All color film, both positive and negative, needs to be stored in cold storage. Color dyes are unstable and will fade unless stored in cold storage. Cold storage will preserve color images indefinitely.

Preservation Microfilm and Microfiche

Preservation microfilm is a microphotographic reproduction of an information resource originally available in paper or other format. This reproduction consists of microimages that are created in a silver-gelatin emulsion applied to a polyester film base. A preservation microfilm should be a camera original film (i.e., "first generation") with the microimages appearing in negative polarity.

The film product, consisting of the base and emulsion, is expected to exist in perpetuity through its manufacture, use, processing, housing, and storage in accordance with established standards and recommended practices without degradation. Applying the term "preservation" to a microform in general carries the expectation that the information sources available for reformatting are as complete as possible and presented in a coherent arrangement; that the physical materials of the film product are of a recognized and established stability; and that efforts need not be undertaken to recreate a microform of the same information source. A preservation microfilm should include explanatory information so that, when a copy is made from the original film, there is easier access and identification of information appearing in the microphotographic reproduction.

Microfilm, Negative, 35 mm, roll

• On acetate base up to approximately 1980, on polyester base after 1980
• First Generation = Preservation Master Negative -stored on a core (This film is exposed in the camera and then developed in a processor as a roll of film with a negative image. This is the most significant film for preservation purposes.)
• Second Generation = Direct Duplicate or Printing Master or Duplicate Negative -stored on a reel (This film is copied from the Preservation Master Negative and is still a roll of film with a negative image.)

Microfilm, Positive, 35 mm, roll:

• On acetate base up to approximately 1980, on polyester base after 1980
• Third Generation =Service Copy or Use Copy or Distribution Copy -stored on a reel (This film is copied from the Direct Duplicate, processed and has a positive image on a roll of film. It is for use in the Reading Rooms, as Loan Copies or as Sale Copies.)
• Microfilm rolls are stored in single reel storage boxes found on pages 21 and 22. All rolls should have wrappers placed around them for identity purposes.

Microfiche

• On acetate base up to approximately 1980, on polyester base after 1980

The Microfiche Service Copy is a third generation positive film cut into single sheets with multiple images (one or many) in a proscribed sequence comprised of a standard number of images. The number of images generally depends on the reduction ratio, but outside dimensions of the microfiche sheet are one standard size that will fit into most microfiche readers in reading rooms.

Polyester

Polyester: One Side Sealed Folder, Seal on Long Side

Polyester one side seal

Uses:

• For housing of individual items

Note: Not suitable for items that have a friable medium such as unfixed pastel, soft pencil, charcoal, or any media that would be affected by the static electricity of the polyester film. Check with your Conservation liaisons if you have further concerns or questions.

Thickness: 3 mil for sizes: smaller or equal to 20" x 24" 4 mil for sizes: over 20” x 24” and up to 22" x 28" 5 mil for sizes: larger than 22” x 28”

Note: Polyester folders need to be ordered with the housing needs of the collection items in mind. There are two basic designs of polyester folders; one with a heat weld seal along the long side, the other with an "L" seal configuration. Each design works better with different collection items. For instance, a fragile thin paper manuscript is difficult to insert into the "L" Sealed Folder. It is more easily placed in the above folder with the static cling of the polyester holding it in place. A heavier manuscript item may fall out of the above folder while being easily held in place using the "L" Sealed Folder.
