Cyndi's List
Cyndi's List of Genealogy Sites on the Internet is a categorized and cross-referenced list of links for genealogical research. The site contains roughly 332,000 links in more than 200 categories. Cyndi's List supplements operating expenses with affiliate advertising. History 
The list was first created as a short list of genealogy bookmarks that was shared with the members of the Tacoma-Pierce County Genealogical Society at the September 1995 meeting. The website opened in March 1996; by the end of that year, it had more than 10,000 links. In 1998 it obtained its own domain name. The site has since received numerous awards. The creator of the site, Cyndi Ingle, formerly Cyndi Howell, is the author of three books on genealogical research and the Internet, including a printed copy of Cyndi's List. In 2012 the links directory of Cyndi's List was duplicated by a rival website. Structure
