Peter Morville is widely recognized as one of the founding fathers of information architecture. 

In this Google Tech Talk, Peter explores the future present in mobile devices, search algorithms, ontologies, folksonomies, findable objects, digital librarianship, and the long tail of the sociosemantic web. Peter challenges us to think differently about the power of search - and findability - to redefine our sources of authority and inspiration in an increasingly digitized and networked information environment.

Clifton reviews another new book on Information Architecture in Boxes and Arrows.

"New Web 2.0 interaction design can offer a lot of new suggestions for easier interactions, good use of white space and other glaring design solutions to the typically very busy space of information architecture. But, if you practice IA well, including some new Web 2.0 techniques, you can begin to create mental space as well as white space. Designing the Obvious: A Common Sense Approach to Web Application Design, a new New Riders book by Robert Hoekman, Jr., is a great place to find out how much mental space can be offered by your systems."
