Published in 2010, U:D/R 03 ThreeSix was the third in a series of research papers published in tabloid newspaper format (36 x 28.5 cm) by Unit Editions.

U:D/R 03 was commissioned by Unit Editions co-founder Tony Brook. In 2008, Brook had been invited as guest speaker at the opening of a MuirMcNeil exhibition which documented 'ThreeEight', an experimental type system that explored the design of geometric alphabets which are distinctive at large point sizes but which can also be read at smaller sizes in bodies of extended text.

A digital reprint of U:D/R 03 is available as a free download from the MMcN shop

The ThreeEight typefaces were subsequently developed further by MuirMcNeil as ThreeSix, an optical / geometric type system of six typeface families in eight weights, published in 2010 and documented in U:D/R 03.
