The BA Manuscripts Center organizes a seminar entitled "Al-Nadim's Book of Cataloging, and the Method of its Critical Publication", on Monday, 18 February 2019, from 12:00 to 3:00 pm, in the BACC Multipurpose Hall. It is delivered by Dr. Ayman Elsayed, manuscripts Researcher and President of the Egyptian Society for Historical Studies. The importance of Al-Nadim's book lies in the fact that it is one of the most important manuscripts that catalogue books and refer to their authors in organized sections that make it easier for researchers to reach what they are looking for.
