BuildingGreen of Battleboro, Vt., has released the second edition of its GreenSpecDirectory, a guide to more than 1,500 environmentally friendly building products. The editorial staff of the company's periodical, the Environmental Building News, chose products whose production, installation, and performance have minimal impact on the environment. "Our tactic was to identify quantifiable, easily verifiable standards where those could be defined," executive editor Alex Wilson says, "then base other decisions about what should be in-cluded on the collective wisdom of our staff."

The directory costs $79 plus shipping. Additional manufacturer literature is also available. Call (800) 861-0954 or visit for more information.
