Hi Jenn, Just to add one example more to the mix, we've built a shelf browser based on Harvard's Stackview/Stacklife project--adding to it a z39.50 connector and organizing results by call number. This search works across all of holdings, regardless of the books' locations. (Click the link, then under the Books and Media box, click See on Shelf to look at our shelf browser.)
