The study did not find authors’ bibliographies in the 1st century AH, but they began to appear in the 2nd after the Arabs knew it from the Greeks, during the movement of translating books from other civilizations. Style of bibliographic description differed between books in the same bibliography, and also between different bibliographies. The bibliographic data was limited and few, in general it consisted of: title, extent, size, subject, notes (included: the field, book evaluation, category of readers/ study level, contents, incomplete books, and date of authorship).
