Here is a list with 1000 directories or link directories on it.
Some time ago Greeneagle got a very useful thread going in which everyone in WPW's virtual community chipped in with lists of directories.
We took this one step further, compiled the whole lot, found a lot more, doubled the list then tested each one four times to see which ones actually worked.
Actually a lot of them just aren't bothered to ever validate your links or have some tricky conditions. We've identified which ones are worth the effort, to save everyone al ot of time.
The whole list can be downloaded for free by going here:

It's free and hopefully of use to all WPW users.
