National Cemeteries Gravesite Locator: http://gravelocator.cem.va.gov
The VA has put a Nationwide Gravesite Locator online, with all the burials in all National Cemeteries nationwide, with the exception of four cemeteries that have not completed their records: Long Island; Los Angeles; Ft. Rosecrans; and the National Memorial Cemetery of the Pacific.
Interment.net has Los Angeles National Cemetery online (85,825 records): http://interment.net/data/us/ca/losangeles/lanat/index.htm
Fort Rosecrans (71,608 records): http://interment.net/data/us/ca/sandiego/rosecrans/index.htm
National Memorial Cemetery of the Pacific (35,224 records): http://interment.net/data/us/hi/oahu/natmem/index.htm
The website says: "Arlington National Cemetery records are also available for interments that occurred after 1999. As more records are added to the database, more burial information will become available. Some state veterans cemeteries can also be searched." The latest: they have added maps of burial sections that can be printed from home computers and at national cemetery kiosks. Once you have entered a veteran's name to search, click on the "Buried At" (burial location) link and a map of the national cemetery is displayed, showing the section where the grave is located. Also, VA recently added to its database the cemeteries in which 1.9 million veterans were buried with VA grave markers, mostly private cemeteries. This addition brings the number of graves recorded in the locator to approximately five million. And they are adding approximately 1,000 new records to the database each day!

There are many vets who are NOT buried in the National Cemetery system. But once the final records are in place, this will cover all those who are. Keep in mind that many of those buried in the VA cemeteries are not vets, but family members. My father is a veteran of the Second World War, and so my mother was eligible to be buried in the Tahoma National Cemetery. When my father dies, his ashes will be with hers, under one shared stone.
Many soldiers who died during the war are buried overseas. My husband's uncle Frank was one such -- we found his grave by searching the American Battle Monuments Commission site: http://www.abmc.gov/.
Here is his listing: http://freepages.family.rootsweb.com/~bobofwa/JohnF_Zimmerman.htm
Whether your vet is gone, or still with you, you can honor him or her at the WWII Registry: http://www.wwiimemorial.com/default.asp?page=registry.asp&subpage=intro It isn't much, but it's something.

The search on the WWII Registry page supposedly searches the ABMC database, but the listing that comes up for John F. Zimmerman is minimal compared to the beautiful page that comes up by directly querying the ABMC site. So it's worth searching both sites, if you don't know where your vet is buried. And of course Interment.net: http://interment.net and Find A Grave: http://www.findagrave.com/ are both worth a look, too.
