Expert Guide Library

Professional Knowledge. Accessible Expertise. Instant Downloads

The DJR Expert Guide Library contains the complete DJR Expert Guide Series along with Discovery & First-Stage Decision frameworks, documenting the DJR Standard for evaluating authenticity, assessing value, and managing risk across complex appraisal, identification, and transactional scenarios.

The library is organized to support disciplined decision-making at defined points of uncertainty. Each guide functions as a self-contained professional reference, emphasizing method, sequencing, and risk control—highlighting critical evaluation criteria, common failure points, and when restraint, escalation, or disengagement is the appropriate course of action.

These materials are relied upon by collectors, resellers, advisors, fiduciaries, and estate handlers to reduce exposure, avoid preventable loss, and make informed decisions before committing to appraisal, authentication, selling, or irreversible action.

Start With Your Situation

If you’re unsure where to begin, start with your situation rather than browsing blindly. These Case Collections are designed to help you identify the safest next step before appraisal, authentication, selling, or irreversible action occurs.

When Professional Review Is Appropriate

The Expert Guide Library is designed to support clear thinking before committing to services. In some situations, however, item-specific judgment is required and cannot be resolved responsibly through general frameworks alone.

When uncertainty remains after self-guided review, a first-stage professional evaluation is available to provide item- or collection-specific clarity before committing to formal appraisal, authentication, selling, or other irreversible action.

This initial review is intended to confirm relevance, identify risk, and determine whether further documentation—or restraint—is warranted.
