National Archives and Records Administration
Provides a comprehensive guide to one of the great treasure troves of U.S. genealogical information. There are very few searchable records online, but the site will help you identify what records the Archives holds, whether they would helpful to your research and where to find them.

The GenWeb Project sites 
Indiana GenWeb
There's a GenWeb site for each state, divided up by counties. What's available at each county site may vary some from place to place, but most should have a queries list (that you can submit to free of charge), a surnames list and a list of some of the basic county resources available in the area. You can log into the Indiana site by itself or log into the U.S. site, which contains a link to each state site. 

Roots Web
This site features several searchable lists, the most important of which is the Roots Surname List. It allows genealogists to make contact with others researching the same surnames as they are. The surname list gives some brief details on time and place and provides contact information, usually an email address.

Ellis Island Records
Allows you to search the transcribed ships' manifests from all the ships that passed through Ellis Island (1892-1924). To view passenger information, you must have a site membership (which is free).  

Ancestry
Ancestry, originally a publisher of genealogy books, has developed one of the premier genealogy Web sites. There are several searchable indexes for free, including Ancestry's World Tree (which features user-submitted family trees) and an excellent Web-based version of the Social Security Death Benefits Index. There are also several for-pay databases available.

Kentucky Vital Records Index
This is the sort of database that everyone wants to find more of. Contains indexes to Kentucky Deaths Records (1911-1992), Kentucky Divorces (1973-1993), and Kentucky marriages (1973-1993). With indexes like this, it really IS easier to do it all at home. 

Ohio Death certificate index
This index, created by the Ohio State Historical Society, allows you to search a list of death records held by the Ohio Vital Records office for the years 1913-1937. Minimal information is available, but it will help you determine death date and location.

Lycos PeopleFinder Switchboard
Looking for living friends and relatives? These sites tap you into nationwide (and worldwide) phone directories which allow you to search for a person in all 50 states at one shot. 

Cyndi's list of genealogy sites on the Internet
Unless your interest is genealogy on Mars, you should be able to find something here. Cyndi offers links to more than 100,000 Web sites, some of which are really databases you can search.

World GenWeb
This site is modeled on the U.S. GenWeb sites. Its goal is to offer a genealogy Web site for each country in the world. It is a mixed bag of some very good sites (Germany and the British Isles), some sites just starting up and some orphan countries. Don't be surprised if the site you are browsing is not in English or is bilingual.

Public Record Locator
A wonderful site containing links to public information databases worldwide. Most of the databases are free.

Find a Grave
Search 41 million grave records and find the famous, the infamous, and the ordinary--frequently with gravestone pictures.

Gen Forum
This site, a subsidiary of FamilyTreemaker's Web site, provides online forums for thousands of surnames and allows users to post queries to them. 

Castle Garden
Most Americans have heard of Ellis Island and assume their ancestors came through this famous immigration center. However, before Ellis Island, which opened in 1892, there was Castle Garden. This very good database offers transcriptions of immigrant ships' manifests from 1820-1892 and allows you to search for your ancestor by name.

www.surnameweb.org
This site allows you to search a surname for country of origin and (sometimes) a name meaning. It also has links to pages with family trees and database hits.
