An excellent article - with some good links - on Jane Jacobs at 2blowhards.
Jacobs, who turns 90 this year, is -- IMHO, but I ain't alone -- one of the most remarkable of the go-it-her-own-way critic-intellectuals of the past century, a proud amateur and generalist from an era that was moving ever more in the direction of professionalism and specialization.
To the links mentioned I would add the wikipedia entries on her and her work - including the discussion around the pages.
