This book; Dirasatul Kashifi Lil Imamil Hafizidh Dhahabiy, is an in-depth introduction to the field of Jarh & Ta’dil; which is the field of debating the reliability of the Hadith narrators.
In addition to the other branches of Hadith sciences, My Honourable Teacher; Al-‘Allamatul Muhaddith, Shaykh Muhammad ‘Awwamah (hafizahullah) has a unique proficiency in this particular one.
I have heard him say several times, that his work on Al-Kashif is a culmination of over thirty years of effort.
Specialists in the field of Hadith need no further introduction to the value of this work.
