Indices in WW-Person
Since there are available:
The classification index.
In the classification index, all persons are classified by the
title/office, i.e. as Emperors, Kings, Landkings, Electors,
Archdukes, Grand Dukes, Dukes, Princes, and Earls.
The next level is a structure if the country/territory was separated
into subcountries/subterrotories (example: Princes of Anhalt by parts
Anhalt-Bernburg, Anhalt-Dessau usw.).
The classification index is now extended to the whole of Europa.
The title lists especially for Portugal and Spain are partially not very
complete. Even so, they are the best you can get at present. Only for
this or that title you get elsewhere more complete lists.
The name index
The alphabetical sorted list of people in portions of 100 persons
starting with some starting person. Sorting is done by first name or
by surname.
