Preventive conservation aims to prevent or minimize damage to library and archival materials, thereby extending their lifespan and preserving their integrity.

While dust can be a nuisance, it is not a major environmental factor that directly contributes to the deterioration of library and archival materials.

The ideal temperature range for storing library and archival materials is 65-75°F (18-24°C), as this range minimizes the risk of damage caused by temperature fluctuations.

The ideal relative humidity range for storing library and archival materials is 45-55%, as this range minimizes the risk of damage caused by humidity fluctuations.

Plastic bags are not recommended for storing library and archival materials, as they can release harmful chemicals that can damage the materials.

Acid-free materials are used to prevent the materials from becoming acidic, as acidic materials can deteriorate over time and cause damage to the materials.

Dust mites are not typically considered a major pest in libraries and archives, as they do not directly damage library and archival materials.

Regular inspections are important for identifying and addressing potential problems early on, ensuring that the materials are being stored and handled properly, and tracking the condition of the materials over time.

Restoration is not a common method for preserving library and archival materials, as it involves altering the original materials, which can compromise their integrity and authenticity.

Digitizing library and archival materials serves multiple purposes, including improving access to the materials, preserving the materials in a digital format, and reducing the need for physical storage space.

MP3 is a common audio format, but it is not typically used for digital preservation due to its lossy compression, which can degrade the quality of the audio over time.

Metadata provides information about the materials, helps organize and manage the digital files, and ensures that the materials are accessible to users.

Tornadoes are not as common as fires, floods, and earthquakes, and they are less likely to cause damage to library and archival materials.

A disaster preparedness plan serves multiple purposes, including minimizing the risk of damage to library and archival materials, ensuring that staff are prepared to respond to a disaster, and providing guidance on how to recover materials after a disaster.

CPR training is not typically considered a necessary type of training for library and archival staff in the context of disaster preparedness.
