Just thought I might plug some software we're developing to solve the book image navigation "misery" that Kyle mentions.
http://ddmal.music.mcgill.ca/diva/
and a demo:

We developed it because we were frustrated with the "image gallery" paradigm for book image viewing, and wanted something more like Google Books' viewer, but with access to the highest resolution possible. We also were frustrated with having to download large PDFs to just view a couple pages.
Diva uses IIP on the back-end to serve out image tiles, so you're only ever downloading the part of the image that's viewable -- the rest is auto-loaded as the user scrolls.
We've used it to display a manuscript that's ~80GB (total), with each image around 200MB.

It's also got a couple other neat features, like in-browser brightness/contrast/rotation adjustments via canvas. (Click the little gear icon in the top left of each page image).
Cheers,
