Gerald R. McMenamin

The first few chapters nicely systematize the field and its applications.
However, the rest is mostly a flurry of words with little real indications on what to actually *do* to decide on a case and how to actually *discriminate* a good decision from a bad one.
All in all, a bit useless - although it has the pro of showing how the "meta-steps" of a linguistic approach are the very same as those of a graphological one.
