Ah ... and here I thought it was environmentally friendly somehow...
(good news for paperbacks I'm fond of, though)

but bad news for all the paperbacks I have hoarded over the last forty

And they disintegrate even more terminally when you open them.
I now have a number of them sitting neatly in plastic folders, but
referring to them is another matter. The compost bin beckons...
