- J, a cappella singing, bridge, history
The PDF for J6.01 is here.
The J Reference Card, a 2-page summary of J primitives, can be downloaded here. This prints in color, and it is a good idea to print on heavy stock so the back of the page doesn't show through to the front. Thanks to Ric Sherlock for the considerable effort of adding color and reformatting the Reference Card for this version.
