Filing

My system of filing books could be described as chaotic. Who am I kidding? It is chaotic.

How do I find my books? I know where they are. A crazy system, but it works. Usually. Honestly. It does.

Until now.

For reasons that are too dull to mention, I need to find the company history of Garton's. The sugar makers. Slim, green and about A4 in size. I can remember what it looks like. Just not where I left it. Where the hell did I put it?

It's not in either of the piles just to my right. Or the one in front of me. Bum, bum, bum. Quadruple bum. Or in my new bookshelf. Where else would I have put it? Surely not upstairs.
