LEOpedia is the LEO Computers Society’s guide to references and holdings related to the story of LEO.

Some items are held at the Centre for Computing History. Other entries simply contain signposts to where the material might be found.

This resource is maintained by Professor Frank Land OBE, with support from CCH as part of our HLF-funded partnership project 'Swiss Rolls, Tea & The Electronic Office: A History of LEO, the World's First Business Computer'.

If any reader knows of any other reference please let Frank Land know at f.land@lse.ac.uk.
