Documents, as one of the most important research sources, are of great importance and value in historical research and are considered to be indicative of the developments of a human society. The aim of this research is to propose new topics regarding the headbook as one of the types of civil records of the Qajar period from two perspectives: external structure and content. The present research method is an analytical archival method that was obtained from examining 15,065 pages of documents available in the Astan Quds Razavi Document Center. The time range of the above documents is 1252-1316 AH. In this research, an attempt has been made to answer the questions of this research by raising the issue of the content and method of organizing these records. The background of the research shows that no independent research has been conducted on headbook so far. The importance of these booklets is that by examining them, useful information can be obtained regarding the civil system of the middle Qajar period. The findings show that the organization of these books had a special order. This book has two chapters of documents and justifications and regulations. The documents chapter is divided into two sections: Abawāb al-Mal and Arbāb al-Tahāwil and Tahāsil. Taxes and other forms are included in the sub-section of Abawāb al-Mal.

The provinces were included in the sub-section of the states of Azerbaijan, Khorasan, Gilan, Mazandaran, Iraq and Fars. The other forms section included the branches of the provinces and other forms.
