The National Institute of Sciences of India, now the Indian National Science Academy, was inaugurated on 7 January 1935 at Calcutta and commissioned its journal, Proceedings of the National Institute of Sciences of India, in the same year for publishing articles from all branches of Science including Mathematics. As the number of accepted papers increased, the journal was bifurcated in 1955 into two parts - Part A (Physical Sciences) and Part B (Biological Sciences). When the National Institute of Sciences of India was renamed as Indian National Science Academy in 1970, the journal became Proceedings of the Indian National Science Academy. It continued to be published in two parts with six issues each in a calendar year. In 1997, the Academy decided to publish only review articles of contemporary scientific interest, evaluating advances and newer approaches in the given field. The emphasis thus shifted from being a vehicle of original research reports into one of reviews, and comprehensive summary reports on chosen topics. Thus from the beginning of January 1998,the Proceedings brought out thematic issues containing invited reviews on current scientific topics. Beginning from the year 2006, the Academy merged the Parts A and B so that each issue of the Proceedings is inter-disciplinary and covers areas under Physical, Biological and Applied Sciences, including Engineering. Four issues are brought out in the months of March, June, September and December each year.

The Proceedings now includes Reviews, Original Research Articles, Commentaries/Opinion/Reflection, Meeting Reports, Book-Reviews, Academy News etc. Reviews and Research papers in Physics, Chemical Sciences, Earth & Planetary Sciences, Engineering & Technology, Material Sciences & Engineering, Plant Sciences, Animal Sciences, Microbiology & Immunology, Cell & Biomolecular Sciences, Health Sciences, Agricultural Sciences are considered for publication. Original research papers in areas of Pure and Applied Mathematics for which the Academy publishes a separate journal, the Indian Journal of Pure and Applied Mathematics (IJPAM), are not considered. However, articles in areas of Pure and Applied Mathematics, which are of interest to a broad readership, and those based on INSA award lectures and reviews/surveys contributed by newly elected INSA fellows and YS awardees can be considered for publication in the Proceedings of the Indian National Science Academy

In addition to the regular issues, Special Issues or Sections on thematic topics are also periodically published. All issues are fully Open Access. All articles, including those invited, are peer-reviewed.
