During several weeks, we have been travelling virtually searching places (some of them do not exist anymore hidden under the sand) that were/are used by caravans in their ways from north to south and from west to east, through the Sahara desert.
Our research group on caravans has done this Google Maps file where you will find a superposition of routes appeared in several books and papers (information collected by Amado Alfadni, Pau Cata, Eleonora Castagnone and Carlos Perez Marin).
LE MAROC SAHARIEN DES ORIGINES À 1670, D. Jacques-Meunié
SUDANESE TRADE IN BLACK IVORY, Ahmed Abdel Ghaffar
THE FORTY DAYS' ROAD, W.B.K. Shaw
CARAVANES D'ALGER AU NIGER PAR LE HOGGAR, Frédéric Nussy
THE TRANS-SAHARAN BOOK TRADE, Eric Rosse
We will complet the map once we get more information
