All three volumes of Al Khamsa Arabians (I in 1983, II in 1993, III in 2008) cover the Al Khamsa Arabian horse, its Foundation Horses, its Ancestral Elements.
Volume II has a time line, beginning in 1800 and running along the bottom of the pages, with dates important to Al Khamsa and how they fit into the world around them. It contains many unusual photos of Al Khamsa Arabian horses gleaned from old sources, many of them lost to Al Khamsa.
There is a different anthology of writings from Al Khamsa breeders. The first presentation of Pre-Registration and Europa horses is contained here. The Pedigree Index and Progeny Index of Al Khamsa horses at that time are printed.
