Prioritizing Web Usability

Hoa Loranger and Jakob Nielsen, 2006

After more than a decade of Web usability research, we literally have thousands of guidelines for making better websites. But what are the most important ones that all designers need to know? That's what Prioritizing Web Usability is about. A second goal of the book is to update the early Web usability guidelines we 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. 406 pages, heavily illustrated, in full color.
