IssueLab - nonprofit research portal

IssueLab, created by the Chicago-based New Media for Nonprofits, collects and shares (or links to) the plethora of nonprofit research out on the Web. As far as I can tell, it's all free, unlike research clipping services. Part of the strategy is that nonprofits register (for no fee) to add their own reports - or add links to their research. There's a wide range of information on the site, from The Almanac of Hunger and Poverty in America 2006 to Health Care and Opportunity - but since it relies on organizations uploading info, there are a few holes (the tech reports section is fairly light, and there's nothing under "Arts and Culture").
