The Organum, as the subtitle of the volume clarifies, includes:

(a) a General Interdisciplinary Terminological Research Center, where the corresponding indexes of the Volumes (I-IX) are cross-referenced alphabetically.

(b) a detailed Summary Table of Contents so that the user of this final Volume can have a panoramic view of the topics discussed by the authors. At the same time, having it at hand saves them from the obligation to refer each time to the Volume of the corresponding field.

But other thoughts can also be entertained by the curious reader: to observe how frequently the same terms are used by different authors. This will highlight influences and affinities that are imposed by the political act itself or by the adoption of concepts that characterize movements, which define thoughts and directions for certain periods.

In the "Notices" of this volume, the reader will be able to seek out the specific reasons that necessitated its compilation.
