Here are some examples of paper catalogues over the years, until electronic methods superseded them, with the red booklet, bottom left, the earliest from the 1950s. The two sheets behind from the 1960s offered a versatile format – folded they could be kept on a desk or in a drawer or, alternatively, pinned to a notice board or wall as a small poster once opened. The transition between the G(eographers’) logo and the A to Z logo is evident, with both appearing on the dark blue booklet. Much cleaner designs, in keeping with the present day logo, came into use in the 1980s. Finally, a steady increase in demand for digital mapping saw a dedicated catalogue introduced in the 2000s.
