NEW YORK - It costs you nothing to discover how much your neighbors are contributing to candidates for president.

Just visit the Web site Fundrace.org (http://www.fundrace.org/) and type your address and ZIP code into the ``Neighbor Search'' tool. You will get a list of what those who live closest to you gave to any of the candidates last year, provided the amount was at least $200.

Your nearest neighbors are listed first, thanks to a technology called geocoding, which matches street addresses with longitude and latitude data.

Visitors can also search by names.

Federal election law makes the snooping possible.

Presidential candidates are required to disclose contributions of $200 or more, and the Federal Election Commission makes databases available for download.

Campaign-contribution data through Dec. 31 is currently available, and the site's developer, Michael Frumin, plans to add more information as it becomes available.

Frumin said Friday that 30,000 to 40,000 people had conducted 100,000 searches since the feature was launched Wednesday.

Fundrace.org is a project of Eyebeam, a New York organization that explores the intersection of arts and sciences.

Other sites have more extensive databases and search capabilities.

Opensecrets.org, run by the Center for Responsive Politics, lets visitors search by state, occupation or employer and has data going back to 1989. It also permits searching of so-called ``soft'' money donations to party organizations, in addition to direct contributions to candidates.

The FEC site (http://www.fec.gov/) also lets visitors do that using its ``advanced search.''
