Cora Num is a fellow of the Heraldry & Genealogy Society of Canberra and has been a presenter, author and contributor to genealogy and family history in Australia and beyond for over thirty years. She has written and published numerous genealogy guides and family histories. In March 2018, Cora was awarded the Australasian Federation of Family History Organisations award for Meritorious Service to Family History.
Cora launched her book Web Sites for Genealogists in July 1997. The 10th and last edition was in 2008. This book evolved from a collection of websites compiled as handouts for adult education classes she was teaching. She established a website in August 1997 to compliment the book. It is online today as coraweb.com.au. The site is older than Google and has attracted millions of visitors over the years.
Cora retired her book business on 30 June 2020
