Although most nominations were by myself, friends and colleagues; and most information was obtained from the web; I did rely on 2 excellent books in some cases.

This book lists a best design for each year of the 20th Century, and has a small blurb about each design. It also gives a small list of happenings during each featured year.
20th Century Design
