Re the Leicester Uni site.
I have been searching for Callister's in the Directories and have noticed not all occurances of the name have been highlighted (hits are indicated with a yellow box) on one occasion there was four Callister's on the same page only two was shown as hits.
fortunatly you can browse the directory a page at a time, doing this I found another three Callister's that had been missed.
So if you don't get a hit,then search for the location and then browse the pages one at a time you maybe lucky
