One of the most complete references on Hamming distances and coding in general was written by Hamming [roman1980coding]
Lee distances have been of interest since 1994, mainly due to the following paper which discusses Lee codes and their relation [hammons1994z]
The Lee distance is been found useful in other contexts [bose1995lee]
