Cite sources so evidence can be found again

A useful citation lets another researcher locate the same record. It is also needed for negative findings or uncertain readings.

The method, step by step

  1. Include repository, collection, archive reference, place, record type, date and entry or page number. For online images add the image number, persistent link and access date.
  2. Attach citations to individual facts, not only the whole person. One record may support a date while contradicting another detail.
  3. Distinguish original image, index, copy and testimony. Two sites reproducing the same record are not independent evidence.
  4. Separate what you read from what you infer and what needs checking. Save a permitted copy with its reuse conditions.

What to record

A useful citation includes repository, collection, reference, record type and date, page or image, URL and access date. For a transcription, name its author and seek the original. State which conclusion the citation supports.

Frequently asked questions

Can I reuse someone else’s published tree?

Treat it as a clue. Find citations, check records and respect reuse conditions. Several trees copying one mistake do not constitute independent evidence.
