The diaries were written between 1915-1922 by Munshi Radha Mohan Lal B.A., a Nazim, a city magistrate in the Princely State of Jaipur, today's state of Rajasthan in northwestern India. There are four diaries in Box 1, each spanning one year, and two short ones in Box 2. They are in good condition and all entries are legible. They are written in English, with very few words, phrases, dates, or notes written in Hindi and Urdu. The latter was one of the co-official languages in the general area. There are entries for every day of the year, with some significant exceptions being the period from January 1917 through March 1918 and from 9 March, 1919 to 30 March, 1919. Some of the front pages contain Nazim's official, professional stamp and the last pages usually contain his random notes in English and Urdu (peoples' names, addresses, quotes, business transactions).

The Nazim led very active and intertwined professional, social, and private lives. From 1915 until circa 1917 he served in Sambhar, then through 1922 in Jaipur. He was the official ultimately responsible for the courts in those cities, which were under the authority of the Council of Regency and the Ministers in Jaipur. Thus he tended to have most contact with 'the Minister' and 'the Resident', with the former serving as his "supervisor". The Nazim also served on a working committee for the board of civil supplies and a committee to control supplies.

The diaries offer great insight into professional, social, and private lives of native provincial officials in the Princely States of British India, into the relationship between native officials and British officials, into the roles rail and commodities, such as salt and sugar cane, played at the time, British India's experience of WWI, into the Satyagraha movement led by Ghandi, and into everyday life in the Sambhar and Jaipur area of the interwar period (pastimes, habits and traditions, religious ceremonies, ailments and diseases from which people suffered, weather and how it influenced agriculture, prices, etc.).
