Materials Processing and Preservation Flashcards

A patron returns a popular fiction book with a single, cleanly detached page. Which of the following is the most appropriate and archivally-sound method for an LTA to reinsert the page?

Answer: Apply a thin, even layer of acid-free PVA adhesive to the binding edge of the page and carefully 'tip it in'.

Applying a thin layer of acid-free Polyvinyl Acetate (PVA) adhesive to the edge of the page and inserting it back into the book's gutter is the correct preservation technique known as 'tipping-in'. This method is strong, flexible, and will not damage the paper over time. Office tape and staples are damaging and not considered archivally safe, as the tape's adhesive will yellow and fail, and staples can rust and tear the paper.

Which of the following environmental conditions is most conducive to the long-term preservation of a library's general print collection?

Answer: A cool, stable temperature and a moderate, stable relative humidity.

Preservation standards recommend a stable and cool environment with moderate humidity (ideally below 70°F and between 30-50% relative humidity) to slow the chemical reactions that cause paper to deteriorate. High heat and humidity accelerate deterioration and encourage mold growth, while direct sunlight causes irreversible fading and damage from UV radiation. Fluctuations are also damaging as they cause materials to expand and contract.

When processing a new hardcover book for circulation, what is the PRIMARY purpose of adding a clear polyester book jacket cover?

Answer: To protect the publisher's original dust jacket and binding from wear, dirt, and spills.

The primary function of a clear polyester jacket cover is to act as a protective barrier. It shields the original dust jacket and the book's binding from damage caused by handling, shelf wear, dirt, and moisture, thereby extending the circulating life of the item.

While processing a donated book, a library technical assistant notices a distinct musty smell and visible fuzzy, discolored spots on the pages. What is the immediate, most appropriate first step?

Answer: Isolate the book in a sealed plastic bag and inform a supervisor.

Mold is a serious biohazard that can spread to other collection materials. The correct immediate action is to contain the contaminated item by isolating it in a sealed bag to prevent spore dispersal. A supervisor or preservation specialist should then be notified to determine the proper course of action, which may include professional remediation or safe disposal. Wiping with a damp cloth can spread the mold, air freshener is ineffective and damaging, and while UV light can kill some mold, it also damages paper.

Which of the following best describes the standard practice for applying a spine label to a new library book?

Answer: Apply the label consistently at a predetermined height from the bottom of the spine across the collection.

Consistency in spine label placement is crucial for efficient shelving, retrieval, and browsing. The standard practice is to apply the label at a uniform height from the bottom of the spine (e.g., a half-inch or one inch) on every book, which creates an orderly and easy-to-scan appearance on the shelves.

An LTA is tasked with physically processing a new paperback. In addition to a spine label and barcode, which of the following steps is most commonly taken to increase its durability for library circulation?

Answer: Applying a clear, self-adhesive laminate film to the front and back covers.

Paperback books are not very durable for repeated circulation. A common and cost-effective method to reinforce them is to apply a clear, adhesive laminate film to the covers. This strengthens the cover, protects it from moisture and dirt, and helps prevent tearing.
