The pages of all 42 argument types in the Periodic Table of Arguments have been revised. Each page now presents a worked example of the type in the same fixed structure, so examples can be compared and the classification can be followed step by step.

Every page opens with a short description of the argument type: what it does, how it works, and where it can be attacked. Then follows the example, first as it might be encountered in the wild and then in its standardized form, with a note on the transformations that were applied to get there. A diagram shows the triadic structure of the example — conclusion, premise and lever — and the classification section explains how the values of the three parameters are determined: the argument form (alpha, beta, gamma or delta), the argument substance (the combination of statement types), and the argument lever, formulated as a statement with a keyword that names the relation between the conclusion and the premise. Each page closes with a list of neighboring types the example should not be confused with, the source of the example, and, where available, additional examples and notes on alternative analyses.
