We wrote on paper by hand, or used a typewriter after they’d been invented in the 1860s. We could use carbon paper to make one or two copies, or a crude type of ink copier, but that was it. If you needed more copies, you’d need to rewrite or retype your document. If you wanted to correct the odd mistake, out came the correction fluid. And if there were lots of mistakes, time to retype. Move paragraphs around, and out came the scissors and glue (hence why we still say ‘cut and paste’).
