Finding people and their whereabouts can be invaluable, whether you're trying to track down witnesses, defendants, or someone who owes money to you or your client. Keep in mind that there are many people finding tools available out there. The websites referenced in this LibGuide represent just a small portion of those. Also, each website listed will have its strengths as well as some weaknesses. Some people will be found easily on some and some may not be found on others.
Also keep in mind that many of these sites will only provide minimal information for free. Details on that person may require purchasing a subscription to that resource.
Whitepages has sections on finding people, locating businesses, performing a reverse phone lookup, and a feature called "Address and Neighbors" which allows you to find out the names of everyone residing in a particular area.
