What to read for GS Mains - Paper 1 ?

Though I have not got a great score in any of the first three GS papers in Mains, I am sharing this list of material to be read for each of the papers because if I had read these sources in depth,I could have got a much better score. This article covers paper one . Subsequent articles cover papers two to four of General Studies - Mains. Syllabus is available here.

Indian Culture

1.NCERT book on Indian art (new), NCERT Ancient and Medieval India (old edition)
2.NIOS Indian culture
3. ccrtindia.gov.in
4. GK Today PDFs on Indian Culture.

Modern India (18th century-1947)

1 "Struggle for Indian Indian Independence" by Bipan Chandra
2."A history of Modern India" by Ishita Banerjee-Dube, this covers from 18th century. Though I have not read this book, I went through the sample chapters and found it to be rewarding.
3.NCERT books

Modern India (1947- )

1.Ramachandra Guha's "India after Gandhi".

2.Bipan Chandra's "India since Independence"

World History

1.Mastering modern world history by Norman Lowe ( Covers everything from 1900)

2.For pre-1900 developments, a basic outline is available in Arjun Dev's "History of the world" and NCERT History books. (For a detailed overview of pre-1900 history,Jain and Mathur's book is good)

Society,Women,Globalisation  :

1.Social Problems in India by Ram Ahuja is an introductory text but it is outdated in terms of data. So,it can be supplemented by selective reading of social issues, women empowerment related articles in The Hindu, Frontline and other periodicals.
2.NCERT books on Indian society

Geography

1.NCERT 9 to 12 - all books

2.Certificate Physical and Human geography by Goh Cheng Leong

3.Geography questions nowadays have become tough and require optional subject-level knowledge.
So,  a selective reading of  Spectrum's guide for Geography or Khullar's Indian Geography  is recommended.

Other than the above, smart and multidimensional reading of newspapers is mandatory.
