Surfing the National Archives and Records Administration's (NARA) Web site <archives.gov> is like rummaging through a pack-rat relative's attic: Rumor has it somewhere amid the boxes of untossables, Great-aunt Eloise has stashed records essential to your ancestral pursuit — but it may require scouring every nook and cranny to uncover them.

Similarly, you may have heard (perhaps via our annual 101 Best Web Sites roundups) that the NARA Web site has loads of genealogical gems. But the organizational method behind the madness eludes many genealogists. And though a recent redesign has made the site more aesthetically pleasing, it still can overwhelm the uninitiated. Never fear: We'll walk you step by step through the NARA maze so you can make the most of this national treasure.
