The Regmi Research Series collection contains 21 bound sets, from Volume 1 to Volume 21 inclusive, comprising a total of 4,292 pages. The original Series was produced in type print on high quality Nepali paper, in the English language. There are a few tables, but the collection is otherwise entirely textual. The Regmi Research Series dates back to 1969 when MC Regmi began translating many of the most important historical documents pertaining to Nepal's law, government, society, politics and economics.

The Regmi Research Series is of great interest to anthropologists, sociologists, historians, lawyers and economists. At its height, only 40 institutional subscriptions of the Series were being disseminated in Nepal and abroad, largely on account of the lack of a distributional infrastructure in Nepal and the unreliability of postal services from this mountain Kingdom.
