Hi, One approach to the UI might be to use Cooliris (was piclens) and generate a media rss file in call number order. It's limited (to people who have installed cooliris) but it's essentially a coverflow. You can do other things within the browser, but few are going to feel as immediate and tranparent to the user. Again, maybe not for all users, but maybe a cool enhanced version for a subset. Generating that media rss file may get tricky (you need uris to thumbs and "fulls") depending on the API from, and agreements with syndetics. -t On Wed, 17 Sep 2008, Charles Antoine Julien, Mr wrote: > I've done some work this. > > > " What I don't know is whether there are any indexing / SQL / query techniques that could be used to browse forward and backword in an index like this." > > Depending on what you want to do exactly, yes.

Could call numbers be placed within a hierarchy? Then display this in an outline view (Windows Explorer) that is also item searchable? Seems to me there is structure in the call numbers that is hidden in current UIs. I also think the actual "Call number" should disappear and replaced by a textual label describing what the numbers mean. > > Fun stuff to think about... > > Charles-Antoine > > > -----Original Message----- > From: Code for Libraries [mailto:[log in to unmask]] On Behalf Of Emily Lynema > Sent: September 17, 2008 11:46 AM > To: [log in to unmask] > Subject: [CODE4LIB] creating call number browse > > Hey all, > > I would love to tackle the issue of creating a really cool call number > browse tool that utilizes book covers, etc. However, I'd like to do this > outside of my ILS/OPAC.
