Joe Beine runs a terrific website that will interest most genealogists. Called Online Searchable Death Indexes and Records, the web site contains a directory of links to websites with online death indexes throughout the USA, listed by state and county. In addition, there are separate indexes for Chicago, Detroit, Los Angeles, New York City, and St. Louis Death Records.
Included are death records, death certificate indexes, death notices and registers, obituaries, wills and probate records, and cemetery burials. You can also find information on the site about searching the Social Security Death Index online.
The web site doesn't always find everything I want but it consistently finds more information about deaths in the USA than any other single web site. I often start first at Online Searchable Death Indexes and Records.
Also, if you use the web site, keep in mind that it does not contain death information on the site. Instead, it points to other web sites that probably contain the information you seek. It works sort of like Google, DuckDuckGo, and other search engines: you the death info you seek (usually the geographic area) and Online Searchable Death Indexes and Records will tell you the most likely web site that will contain the details.
Joe Beine has just announced a major upgrade to the site:
