According to a legend, Thomas W. Holley of Holyoke, Massachusetts, invented the legal pad around the year 1888 when he innovated the idea to collect all the sortings, various sort of substandard paper scraps from various factories, and stitch them together in order to sell them as pads at an affordable and fair price. In about 1900, the latter then evolved into the modern legal pad when a local judge requested for a margin to be drawn on the left side of the paper. This was the first legal pad.
In 1902, J.A. Birchall of Birchalls, a Launceston, Tasmania-based stationery shop, decided that the cumbersome method of selling writing paper in folded stacks of "quires" (four sheets of paper or parchment folded to form eight leaves) was inefficient. As a solution, he glued together a stack of halved sheets of paper, supported by a sheet of cardboard, creating what he called the "Silver City Writing Tablet".
The only technical requirement for this type of stationery to be considered a true "legal pad" is that it must have margins of 1.25 inches (3.17 centimeters) from the left edge of legal pad. Here, the margin, also known as down lines, is room used to write notes or comments. Legal pads usually have a gum binding at the top as opposed to a spiral or stitched binding.
