Donations to U.S. groups' relief efforts in Haiti have reached $78 million and climbing, according to the Chronicle of Philanthropy.

For people thinking of contributing, here are a few resources with tips for safer and more effective giving.

Charity Navigator has put out a list of organizations working in Haiti, their history of work there, what they are providing and their charity rating. Clicking on the name of the organization provides details such as a financial report and how much the top executive is paid.

Another good resource is the Better Business Bureau's Wise Giving Alliance, which lists charities working in Haiti that meet its standards, and has a special section with advice on giving by text message.

In our region Philanthropy Northwest and Global Washington are both updating their Web sites with news about local donations and local organizations working in Haiti.

The FBI warned on Thursday that scam requests for donations are likely, reminding Internet users who receive appeals for money in the aftermath of Tuesday's earthquake in Haiti to apply a critical eye and do their homework. The FBI advised:

--Don't respond to unsolicited emails
--Be skeptical of anyone representing themselves as a survivor needing help through email or social networking
--Verify non-profits through independent Internet searching rather than following links
--Make contributions directly to known organizations
--Don't give out personal or financial information to anyone who solicits contributions
