How do family historians know they are producing or receiving
trustworthy results? This official manual from the Board of
Certification for Genealogists, essentially a users' guide for family
historians, provides standards for genealogical researchers to assess
their own and others' work. The revised second edition increases the
clarity of DNA and privacy standards. Those standards are especially
useful in the twenty-first century, when many genealogists use a complex
new tool--DNA testing--and trace living people more often than they did
in the past.
