This is the updated version. Not a sequel or a new edition, but:
A second goal of the book is to update the early Web usability guidelines I published in the 1990s. All the guidelines found since 2000 continue to hold, but what about findings from the studies we conducted 1994 to 1999? The book compares these old studies with more recent ones and explains which of the old guidelines should still be followed.
There is drool on my chin right now. Is that wrong?
