Ibrahim Al -Abyari says about this book: The first thing that I received with this manuscript was the day I was a professor at the Egyptian Institute in Madrid, and she sat to the disciples of Dr. Abdulaziz Al -Ahwani, the institute's agent, that time, we read the sigge of the Ascorial Library. We were keen on what we would go out to the people as a index of this library, and this manuscript was a share, so I went to read and then copy, and what I took from that first step until I increased the belief in the destitution of the Arab library to a lot of organized effort. Al -Abyari presented us with this book from the great literary heritage of the Arab Library.
