The topic scares me.
Anyway, I am only comparing libraries in Malawi and what I have seen at Robert Gordon University. While we still have security guards in our libraries embarrassing patrons with 'police' searching, technology can provide a labour free, and extensive security system.
Sometimes I think that while dreaming in colour is good, the cost of living the colourful dreams are so huge. Maintaining an electronic security system is expensive, the gains are so huge. Whither African libraries!
