Picturing your digital library (or not)

Everyone’s brain is different. I’ve known that mine is different in a particular way since I was at secondary school. I can’t picture things in my head. It doesn’t matter what you describe – a sunny beach, the Drill Hall Library where I work, members of my family – I simply cannot “see” it unless it’s right there in front of me. Apparently, this is unusual, though to me it’s perfectly normal.
