Did you know that O’Reilly has published the 4th edition of this seminal work, Information Architecture: for the Web and Beyond, by Peter Morville and Louis Rosenfeld first published in 1998? Terrific! And I just got my copy. The first section introduces IA with definitions and issues then discusses design for finding and for understanding. Part 2 covers the basic principles of IA including organization systems, labeling systems, navigating systems, search systems as well as thesauri, controlled vocabularies & metadata. Peter is a wonderful teacher and speaker about these topics for librarians, info pros, taxonomists, and knowledge managers. He will be participating in Library Leaders Digital Strategy Summit at the DC Hilton, March 8-9.
