Building a Documented Wood Collection

A documented wood collection is more than a group of samples. It is a structured reference archive that preserves species identity, origin, and physical characteristics for long-term study.

Whether assembled by a collector, woodworker, educator, or institution, proper documentation transforms individual samples into an educational resource.

This guide outlines how to build and maintain a structured hardwood collection.

Define the Purpose of the Collection

Before acquiring samples, determine the scope.

A collection may focus on:

  • Regional hardwoods
  • CITES-listed species
  • Density comparisons
  • Grain structure variations
  • Historic trade species
  • Plantation vs wild-grown material

Clear scope improves organization and long-term relevance.

Standardize Sample Dimensions

Uniform sizing enhances comparison and storage efficiency.

Common collector formats include:
1/2 × 3 x 6 inches
Small turning blanks

Consistency allows for easier storage, labeling, and display.

Labeling Requirements

Every sample should include clear documentation.

Minimum recommended information:

Common name
Scientific name
Region of origin
Date acquired
Source or supplier

Additional documentation may include:

Density rating
Janka hardness
CITES status (if applicable)
Moisture content at acquisition

Accurate labeling prevents misidentification over time.

Scientific Names Matter

Common names vary across regions and markets.

Scientific names provide:

  • Taxonomic clarity
  • Regulatory accuracy
  • Trade consistency
  • Long-term reliability

Whenever possible, document both.

Documenting Source & Provenance

Provenance adds educational and archival value.

If known, record:

  • Country of harvest
  • Harvest method (plantation vs wild)
  • Supplier
  • Certification status

This information strengthens long-term historical context.

Photographing Samples

Photographic documentation preserves:

  • Initial color
  • Grain structure
  • Surface texture

Best practices:

  • Use consistent lighting
  • Photograph both face and end grain
  • Avoid heavy color correction
  • Store images with metadata

Comparative photography becomes valuable as samples age.

Organizing the Collection

Organize samples logically.

Options include:

Alphabetical by scientific name
Grouped by region
Grouped by density class
Grouped by trade status

Choose one consistent structure and maintain it.

Environmental Control

Maintain stable storage conditions:

Temperature: 60–75°F
Relative humidity: 35–55%

Avoid:

Direct sunlight
Basements without climate control
High-humidity storage

Environmental stability protects structural integrity.

Tracking Changes Over Time

Long-term collections benefit from:

Periodic inspection
Updated photographs
Moisture measurement checks
Color progression notes

Wood is dynamic. Documentation should reflect that.

Educational Value

A documented collection serves as:

  • Identification reference
  • Structural comparison tool
  • Sustainability study resource
  • Trade history archive

Structured documentation increases research credibility.

Highly figured or historically significant species such as Zebrawood, Bubinga, Purpleheart, Bloodwood, and Black Walnut are frequently prioritized in documented collections due to their distinct grain structure, color characteristics, and trade history. Including visually and structurally diverse species strengthens comparative reference value.

Ethical & Legal Considerations

Ensure samples are:

Legally sourced
Compliant with CITES when applicable
Properly documented

Maintain transparency in acquisition records.

Expanding the Collection

As the collection grows:

  • Maintain consistent labeling standards
  • Avoid duplicate undocumented specimens
  • Record species not yet represented
  • Consider contributing duplicate samples for educational exchange

Growth should be intentional, not random.

Digital Documentation Layer

In addition to physical storage, maintain:

Digital catalog spreadsheet
Photographic archive
Species cross-reference notes
Acquisition log

This creates redundancy and improves research utility.

Institutional Note

A documented wood collection represents both biological diversity and trade history. Accurate labeling, environmental control, and structured organization transform individual samples into an enduring reference archive. Preservation and documentation ensure long-term educational and structural value.
