There are many academic journals around and new ones are emerging all the time. One quite new that seems to have quite interesting content to anyone in HCI and interaction design is the Journal of Information Architecture. All the content seems to be free online, at least the current issue is.
It is also interesting to see how the field of HCI, interaction design, information architecture, experience design, are all blending into something new. Even product design and "real" architecture is part of the mix. All this is of course a natural reflection of the technological development where physical material is combined and infused with digital material and all products become a new form of artifacts that needs to be designed as a whole.
And since it is that time of year. Happy New Year!
