Use the result while planning ingest, digitization, quality control, reporting, or preservation work where the stated rule needs to be repeatable and reviewable.

Previous month

Reference questions answered in the previous month.

Current month

Compute the month-over-month percent trend in archival reference desk question counts with the absolute change and its direction. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Trend percent

Percent change from the previous month.

Absolute change

Question count difference between the months.

Direction

Direction of the month-over-month change.

• Repository policies, format profiles, equipment capabilities, and descriptive standards vary. Preserve the source value and record the rule version instead of treating this utility as an authority-record or preservation-system validator.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Complement the calculation with format validation, fixity checks, provenance records, and human review. For policy decisions, apply the profile adopted by the repository rather than an undocumented local convention.
