I've been waiting for these photos --thanks!

I think you could write an article about creating book displays. You obviously have a knack for putting together ideas and simple materials into something eye-catching. Possibly the very act of pulling some titles off the shelf and out where the cover is visible is enough of an innovation at most libraries. Patrons like the bookstore model.
I'm also curious about what makes or breaks a display. It's a great opportunity to pull in the [url http://www.wired.com/wired/archive/12.10/tail.html ]Long Tail[/url] of books that are not in the immediate eye of the public. Maybe the better you can make the connections between books (like Amazon's "you might also like ..."), the more you arouse the curiousity of the reader?
Keep up the good work.
