Sources & Attribution

A source citation should identify the work and the relevant edition or date. Preserve the context needed to interpret the cited material.

Use original documents where they address the question. A later summary is identified as such rather than presented as the original finding.

Keep quotations accurate, attributed and within the permission applicable to the source. A quotation does not imply endorsement of the new work.

Describe the origin, definitions, period and transformations of data used. Public visibility alone does not establish permission for bulk reuse.

Use material with an appropriate license or permission. Credit the actual creator and identify substantive adaptations.

Do not publish private information merely because it was submitted for review. Use the agreed information-handling procedure.

Report a source error with the publication, passage and original reference.
