Note Pad, Legal pad, paperback book, writing tablet ect ect invented by Australian JA Birchall 1902.

JA Birchall of Tasmanian stationery company Birchall, was the first person to take loose sheets of paper, cut them in half, back them with cardboard and glue the top edge. He sold them as the Silvercity Writing Tablets, and the idea went on to give rise to none other than the humble paperback book binding, thus enabling the booming new genre of pulp novels.
