Time does fly, life is finite, and we all end up facing our maker, sooner or later.
And that's where Interment.net comes in. This site lists records from thousands of cemeteries around the world. Transcripts of cemetery records can be uploaded by anyone, so you never know quite what you might find at the site.
A typical cemetery record will include a brief description of the cemetery itself (often with driving directions), along with the actual inscriptions from gravestones. Since these are user-submitted transcripts, there's a lot of variability in the records.
The big storm of 1905!
It's difficult to say how large a dataset is here at Interment.net, but searching is easy, so it's certainly worth a look.
Most of the records appear to be from cemeteries in the US and Britain, although coverage is truly worldwide, and includes Australia, New Zealand, Canada, Germany, Belgium, Poland, Mexico, Carribean, France, Japan and Cyprus, among others.
There are other important sites that allow searches of cemetery records, including Find a Grave, Deceased Online, and the Veteran's Gravesite Locator.
