After all these years I finally figured something out yesterday. Why lever-arch folders have those big holes in the spine. It's so you can hook your finger inside and easily remove them from the shelf! What ingenuity! And all this time I thought it was a wee porthole for the papers to peep out of. Sadly, this has been the state of my brain this week. Almost as profound as the day I discovered the marvellous invention that is the staple remover. Apologies for all the waffle and obituaries lately. I shall reboot brain and post properly on the weekend.
