This bibliography is a supplement to the one previously published by Brill in 1988. This one covers material from 1984 to 2003. The chronology has been expanded to begin in the fourth century. Numerous Iberian Church Fathers not represented in the first one are now incorporated. The book contains author and subject indexes and is cross-referenced throughout.

Since 1987 we have defended in articles that the Spanish queen Isabella I of Castile (Isabel la Catolica) was the new chess queen (dama) on the chessboard. Other publications were in 1990, 1994, 1997, and 2004. And of course, Marilyn Yalom studied our book during her visit to the National Library in The Hague (Holland) before she wrote Birth of the Chess Queen in 2004. In her book one cannot see that in 1987, 1990, and 1994 we already published material about Isabel la Catolica (Isabel I of Castile) being the new powerful dama or chess queen on the chessboard. In other words we can state here that we have been studying Spanish history and its chess literature for over 30 years. Since 2003 we have also known the development of the new bishop in chess."

Scholars did not consider it necessary to grant Spain the honour of being the creative country of the game of draughts and of the new modality in the chess game with the new dama. Both the alquerque-3 as the alquerque-9 games were known in Roman times. Completely different is the situation for the alquerque-12 game. It is said that the alquerque has its origin in Egypt. Perhaps this is the case for the alquerque-3 and alquerque-9 games, but never for alquerque-12 game. Some authors claim that the alquerque-12 game is a Greek or Roman game, but the great expert of these games, Dr. Ulrich Schadler, discards it. This book is the first proof that the alquerque-12 game was not popular at all in France, but much more in Spain, where the new chess game and draughts game were invented.

The first Spanish books about the game of draughts have a very high standard and date from the XVI century, while the first French book comes from the XVII century and the game description is very basic. Contrarily to this evidence scholars did not consider it necessary to grant Spain the honour of being the country of creation of the game of draughts and of the new modality in chess with the new dama. Both the Alquerque-3 and the Alquerque-9 games were known in Roman times. The situation is completely different for the Alquerque-12 game. It is said that the Alquerque has its origin in Egypt. Perhaps this is the case for the Alquerque-3 and Alquerque-9 games, but never for Alquerque-12. Some authors claim that the Alquerque-12 game is a Greek or Roman game, but the great expert of these games, Dr. Ulrich Schadler, discards those theories. The first volume of the Alquerque-12 game unravels France and Spain. The second volume deals with the remaining countries of the world."
