This book is an introductory list of those eminent books that had been written hundreds of years ago. The author has taken pains in collecting such books and classified under eleven different faculties. It is neither research oriented nor planned as a text-book to a comma and a colon. The main objective is to introduce the author and the book as briefly as possible. For this purpose relevant information has been brought together and compiled in a simple readable form. As far as possible, information has been drawn from the original texts or their translated editions, and also from secondary sources and reference works. We can see Islamic civilization, culture and thought in these books and can evaluate their achievements through comparing with modern civilization.
