5-1/4 inch computer disks Many of the computer disks at J.52-J.93 cannot be read at this stage. Ten of them (J.60-J.62, J.69, J.70, J.81-J.85) have been successfully accessed with the generous help of Dr Jeremy John, the Curator of Digital Manuscripts at the British Library. Their contents have been preserved in the form of a CD at J.94; for a list of contents, see J.95. 1988-2007
