Regmi functioned as a solitary historian at the Regmi Research Centre (sometimes called Institute), administratively helped by a small group of non-academic assistants, including, in the later years, his brother Rabish C Regmi and son Suresh C Regmi. Individuals such as Shankar M Amatya and Krishna M Arjyal helped Regmi go through thousands of documents held at the Records Office (‘Lagat Phant’) of the Department of Land Revenue in the Ministry of Finance, the Ministry of Foreign Affairs, the library of the Ministry of Law and Justice, the Department of Survey, offices under the Guthi Corporation which look after the lands that once paid for the upkeep of Kathmandus temples and other public structures, and the Pashupatinath Temple. Documents from the above-mentioned sources were collected most intensively in the 1960s and the 1970s and were transcribed into thick volumes. These volumes, which were later referred to as the Regmi Research Collections, filled up the shelf space in his study and became Regmis personal archive based on which he produced 14 books on the economic and political history of 18th and 19th century Nepal. The first of these books was Some Aspects of Land Reform in Nepal (1960). It was followed by the four-volume study entitled Land Tenure and Taxation in Nepal (1963, 1964, 1965, 1968, Institute of International Studies, University of California at Berkeley; reprinted in a single volume in 1978 by
Ratna Pustak Bhandar, Kathmandu). In 1971, Regmi published A Study in Nepali Economic History 1768–1846 in the Bibliotheca Himalayica series (started by late H K Kuloy) of the Manjusri Publishing House and five years later, the
University of California Press published his Landownership in Nepal. These two works along with the earlier four-volume study established Regmi as a world-class scholar and in 1977 he became the first Nepali to receive the Ramon Magsaysay Award, receiving it for the “journalism, literature, and creative communication arts” category. The award was granted to him in recognition of his "chronicling of Nepals past and present, enabling his people to discover their origins and delineating national options." Regmi published two books in the next two years: Thatched Huts & Stucco Palaces: Peasants and Landlords in 19th Century Nepal (1978, Vikas) and Readings in Nepali Economic History (1979, Kishor Vidya Niketan). In the decade of the 1980s, he published The State and Economic Surplus (1984, Nath Publishing House) and An Economic History of Nepal, 1846-1901 (1988, Nath Publishing House). In the following decade Regmi published Kings and Political Leaders of the Gorkhali Empire 1768-1814 (1995, Orient Longman), and Imperial Gorkha: An Account of Gorkhali Rule in Kumaun 1791-1815 (1999, Adroit). His last book Nepal: An Historical Miscellany (2002, Adroit) is a collection of various primary and secondary texts, translated into English from the original Nepali with additional commentary. At least ten of Regmis books are of outstanding quality and it is certain that they will continue to be the most influential texts of economic history of 18th and 19th century Nepal for at least another generation. He is the most appreciated but less read historian of Nepal. ==Paying for His Work==
