Saw this article in Wired News today about Hypertag technology: Wired News: Cell Phones, Billboards Play Tag.

The idea is to attach little smart tags to all variety of displays (billboards, posters, musuem exhibits) that would allow users of mobile technology to access digital content about the display. So you could go to a museum, check out the mummy exhibit and call up relevant web materials related to mummies.

There could be endless applications for this. How about we put these Hypertags in every book on our shelves? The user points at a book and immediately the OPAC listing appears, or the NYT book review, or even, dare I say it, Amazon reader opinions. Maybe we can use Novelist and the like to call up a page of related books based on our catalog's descriptors. See where I'm going with this? Seems like we should be keeping our eyes on this technology and our minds open to the possibilities.
