I went to Belfast's Central Library music department to borrow a classic CD recently.
I found the CD number in the file, but when I took the details to the counter I was told that I would have to search for it on the shelves, as they were not filed in CD number order.
This proved to be a frustrating activity as many of the CDs were misfiled and, in any case, did not show a CD number on the outside of the case.
The cases were sealed and in many of them there were labels stuck in places that made it impossible to read what was on the CD.
I have had no similar difficulties in libraries in England and I find it hard to accept that the Belfast situation is so chaotic when one knows that computer-based systems could solve the problems.
