How do I conduct a preservation needs assessment of an archival collection?

A preservation needs assessment is a structured survey of a collection’s physical and environmental condition. Its goal is not to fix every problem at once, but to understand risks across the whole holding and decide where limited resources will do the most good. The process works for paper, photographs, audiovisual media, and born-digital materials alike.

Define scope and gather context

Start by clarifying what you are assessing: a single collection, a storage area, or an entire repository. Review existing documentation such as accession records, finding aids, and prior condition reports. Establish why the materials matter — their administrative, legal, historical, or research value — so that preservation effort can be weighed against significance.

Survey conditions

Examine the materials and their environment systematically. Look at:

• Item and collection condition — embrittlement, tears, mold, pest activity, fading, broken bindings, or media degradation.
• Storage environment — temperature, relative humidity, light exposure, air quality, and stability over time.
• Housing and handling — boxes, folders, and enclosures; how items are shelved, retrieved, and used.
• Building and disaster risks — water sources, fire suppression, security, and emergency readiness.

For digital materials, assess file formats, media stability, redundancy of copies, and whether content remains accessible on current systems.

Analyze and prioritize

Translate observations into risk levels. A common approach ranks issues by both likelihood and potential impact, distinguishing problems affecting many items (such as poor climate control) from those affecting a few high-value pieces. Environmental and disaster risks often deserve attention first, because they threaten entire collections rather than single objects.

Document and recommend

Record findings in a written report that describes conditions, identifies priorities, and proposes phased, realistic actions — improved storage, rehousing, environmental monitoring, reformatting, or staff training. Note what can be done in-house versus what may require a conservator. Treat the assessment as a baseline you can revisit, since conditions and collection use change over time.
