I'm trying to find an industry directory for design agencies in web design for the US market. For instance, in fashion, there is a "who's who" called LE BOOK, and everybody in the business wants to list themselves with them. I found Ad Age's list, but its focus seems to be on traditional media. I checked out a few others as well, but they all look kind of sketchy, and I'm not convinced any of them is a definitive reference.

If you have any suggestion, I'd appreciate it. Thank you for your time.
