I spoke a bit soon perhaps. I tried this on some different libraries and
it seemed to work on most, but not all. Maybe a version bug. I'll look
into it more later.

Hmmm, sounds interesting. I have a deadline fast approaching, so I
probably won't do it for this collection. It's something to keep in mind
for future searches.

I have customized the interface to some extent, including manipulating a
bit the search page layout.

As I mentioned a bit earlier I'm working with an unfortunate deadline ;).
But being the perfectionist that I am I'll probably attempt to go back
until I'm content with the project at some point in a month or two. So
I'll probably be back.


Thanks for the pointers though, it sounds very useful.
