Nonprofit and business leaders in Silicon Valley have unveiled a plan to use a $300,000 grant from the Packard Foundation to encourage charitable giving by the area's entrepreneurs, the San Jose Mercury News reports.

The campaign will target more than half of the area's residents who said in a survey conducted last year by Community Foundation Silicon Valley that they would donate more if they believed the money was being spent wisely.

``We hope to challenge people to step up to the bar,'' says Steve Kirsch, chairman of Infoseek Corp., which supports the community with its own $25 million fund for giving.

Plans for the campaign, which targets the business world, include establishing:

• a Web site that will provide information on how to find nonprofit groups, what they do and which are the most needy.
• a ``catalog of giving'' that will provide information on nonprofit projects.
• a 10 Percent Club that will seek out large donors and challenge them to set aside money to create a foundation.
• a plan to encourage new Internet groups to follow the example of eBay, which created a foundation with pre-initial public offering stock.
• an effort to get Silicon Valley business leaders to join nonprofits' boards to see firsthand what impact they have on communities.
