Dorothy Brown, the circuit court clerk for Cook County, Ill., has found a new way to raise revenue for her cash-strapped operations: selling advertising to law firms on her office’s Web site.

At least five Chicago-area law firms have taken the opportunity to showcase their services on the circuit court’s home page (www.cookcountyclerkofcourt.org), placing flashing color ads for representation in DUI cases, divorce proceedings and home foreclosures. Sales of the ads, which click through to the firms’ Web sites, have been so successful that Brown said she’s looking for ways to expand the ad space.
