A compendium of original articles and essays from leading thinkers in the computer industry, including Alan Kay, Nicholas Negroponte, and Don Norman, surveys the range of issues relating to interface design.
To be sure, this book is now (very--1990) dated (as evidence, consider the consciousness-raising contribution by Timothy Leary). Yet there is still value in going back and reading some of these seminal essays by such luminaries as Brenda Laurel, Alan Kay, Donald Norman, Nicholas Negroponte, Bill Buxton, et. al. Out of print, but still available if you want to get it--in fact used copies go very cheap (as do books by Timothy Leary).
