PSIR Optional Booklist 2027
Section-Wise Reference List
Four sections, four separate literatures. Which book serves which section, why Paper II Section B cannot be finished from books at all, and the order to read them in.
Political Science and International Relations is examined in four distinct sections, not two papers. Political theory, Indian government and politics, comparative politics and international relations, and India's foreign policy each have their own literature, and a book that serves one serves the others hardly at all.
This is the fact that shapes the reading list. Candidates who think in terms of "Paper I books" and "Paper II books" end up over-reading one section and leaving another thin. The list below is arranged by section, which is how the syllabus is written and how the questions are set.
A second point worth stating early. Section B of Paper II cannot be finished. India's relations with its neighbours and the major powers move continuously, which means that section is served less by books than by a file maintained through the year. The books establish the framework; the substance accumulates.
This page sets out the reference list for the 2027 cycle, arranged by section and by the units each source serves. The optional must be declared in the application form between 13 January and 2 February 2027, and both papers are written at the Main Examination beginning 20 August 2027.
How to Use This List
- Read by section, not by paper. Each of the four sections has its own core text. Working through them in section order produces a coherent sequence; working through them in book order does not.
- Start with the NCERTs. The Class XI and XII Political Science volumes cover political theory, the Constitution, Indian politics since independence and contemporary world politics. They are the cheapest and fastest orientation available.
- Theory before application. Section A of each paper supplies the frameworks that Section B answers are built on. Reading Indian politics before political theory, or foreign policy before international relations theory, produces descriptive answers.
- One book per unit, finished. Where alternatives are listed they are alternatives, not additions.
- Keep a country file alongside the books. For Paper II Section B, one page per major relationship and per institution, updated through the year. No book will carry this section to August.
Political Theory and Indian Politics
The theory section: political concepts, thinkers, ideologies and Indian political thought.
| Book | Author | Units served |
|---|---|---|
| Political Science, Classes XI and XII | NCERT | Foundation — read first |
| An Introduction to Political Theory | O. P. Gauba | Political theory, state, justice, equality, rights, democracy, power |
| Western Political Thought | Brian R. Nelson | Plato to Arendt — the thinkers unit |
| A History of Political Thought: Plato to Marx | Mukherjee and Ramaswamy | Alternative for Western political thought |
| Indian Political Thought | V. R. Mehta or Bidyut Chakrabarty | Dharamshastra, Arthashastra, Aurobindo, Gandhi, Ambedkar, M. N. Roy |
| Issues in Political Theory | Catriona McKinnon | Contemporary debates — useful for applied and comparative questions |
On Gauba. The workhorse of this section. It covers most of the concept units at the right depth and in accessible prose, and it should be the first book after the NCERTs.
On Nelson. Western political thought is the unit candidates most often underprepare and the one that most rewards precise attribution. Questions ask what a thinker argued and against whom, which summaries do not carry.
On McKinnon. Not a core text, but valuable for the contemporary framing of justice, rights and democracy that the Commission increasingly favours over textbook exposition.
Indian Government and Politics
Nationalism, the Constitution, institutions, federalism, parties, social movements.
| Book | Author | Units served |
|---|---|---|
| Indian Government and Politics | B. L. Fadia | The primary text for this section |
| Indian Polity | M. Laxmikanth | Constitutional provisions, institutions, commissions |
| The Oxford Companion to Politics in India | Jayal and Mehta | Analytical essays — parties, federalism, caste, movements |
| India's Struggle for Independence | Bipan Chandra | Indian nationalism, freedom struggle perspectives |
| India Since Independence | Bipan Chandra | Post-independence politics, planning, party system |
It supplies what an institution is; PSIR asks how it has actually worked and why it departs from its envisaged role. Used alone it produces General Studies answers. The Oxford Companion essays supply the scholarly attribution — Kothari on the Congress system, Brass on ethnicity, Kohli on the state — that distinguishes a PSIR answer from a polity answer.
Comparative Politics and International Relations
Comparative method, the state in comparative perspective, globalisation, IR theory, key concepts, the international order and global concerns.
| Book | Author | Units served |
|---|---|---|
| Global Politics | Andrew Heywood | IR theory, key concepts, global institutions, contemporary concerns |
| The Globalization of World Politics | Baylis, Smith and Owens | Alternative and supplement on IR theory |
| International Relations | Peu Ghosh | Accessible treatment of theory and the international order |
| Comparative Government and Politics | J. C. Johari or Vishnoo Bhagwan | The comparative politics units |
On Heywood. The most useful single text in the whole subject. It covers IR theory, concepts, institutions and global issues in readable prose and repays several passes.
On the comparative politics units. This is the thinnest part of the available literature. No text covers it as well as Heywood covers international relations, and candidates should expect to assemble material rather than find it in one place.
India and the World
Indian foreign policy: determinants, the neighbourhood, the major powers, multilateral institutions, the nuclear question, recent developments.
| Book or source | Author | Units served |
|---|---|---|
| Does the Elephant Dance? | David M. Malone | Indian foreign policy — determinants and conduct |
| Challenges and Strategy: Rethinking India's Foreign Policy | Rajiv Sikri | Neighbourhood, major powers, strategic questions |
| India's Foreign Policy: Coping with the Changing World | Muchkund Dubey | Alternative analytical treatment |
| Pax Indica | Shashi Tharoor | Contemporary framing, readable overview |
| India's Foreign Policy and Its Neighbours | J. N. Dixit | The neighbourhood, historical depth |
| Annual report, joint statements and briefs | Ministry of External Affairs | The authoritative Indian position, current material |
On the books in this section. They establish framework and historical depth. None of them is current, and none can be, which is why this section rests on a maintained file rather than on reading alone.
On the MEA material. Annual reports and official statements give India's stated position, which is what the paper asks for. A candidate quoting the official framing is on firmer ground than one paraphrasing commentary.
↑ Back to topContemporary Material
| Source | Use |
|---|---|
| One newspaper editorial page, consistently | Foreign policy and domestic political analysis |
| Ministry of External Affairs website | Bilateral briefs, joint statements, treaty texts |
| Strategic and defence studies publications | Security analysis, nuclear and regional questions |
| Economic and Political Weekly, selectively | Indian politics, federalism, party system |
| Sansad TV discussions | Depth on contested foreign policy questions |
| Previous year question papers, ten years | The most reliable guide to depth and framing |
Maintain this as a syllabus-mapped file — one page per major relationship, one per institution — rather than as dated clippings. A file organised by unit is usable in August; a folder organised by date is not. The international relations current affairs section of this site is organised the same way.
What This List Deliberately Omits
- Multiple books on the same section. PSIR has more available literature than any other optional discussed on this site, and that is a hazard rather than an advantage.
- Original texts of the political thinkers. Reading Hobbes or Rawls in the original is admirable and impractical within a preparation timeline. Nelson and Gauba carry what the paper asks.
- Area studies monographs. Deep treatments of particular bilateral relationships overshoot the syllabus.
- News aggregation as a substitute for theory. A candidate who follows foreign policy closely but has not read international relations theory can describe events and not analyse them.
The working total is eight or nine sources across the four sections, plus the maintained current file. That is larger than most optional lists, which reflects the size of the syllabus rather than any inefficiency.
Reading Sequence
| Stage | Reading |
|---|---|
| First | NCERT Political Science, Classes XI and XII |
| Second | Gauba — political theory and concepts |
| Third | Nelson — Western political thought; then Indian political thought |
| Fourth | Fadia and Laxmikanth — Indian government and politics |
| Fifth | Heywood — international relations theory and concepts |
| Sixth | Comparative politics material |
| Seventh | Malone and Sikri — Indian foreign policy |
| Throughout | Oxford Companion essays by topic; country file; previous year papers |
Heywood before the foreign policy books is deliberate. Section B of Paper II is written using the frameworks Section A supplies, and reading it the other way round produces description in place of analysis.
Common Mistakes with the Reading List
- Reading foreign policy before international relations theory. The commonest sequencing error, and it shows in answers that narrate rather than analyse.
- Treating Laxmikanth as sufficient for Section B of Paper I. It supplies institutional facts, not the analytical framing this subject requires.
- Underpreparing Western political thought. It carries weight and demands precise attribution, and it is the unit candidates most often postpone.
- Buying more books because the syllabus is large. Eight sources read properly beat fifteen sampled.
- Relying on a book for Paper II Section B. No published book is current enough. The file is the source.
- Ignoring previous year papers until late. Themes recur visibly in this subject, and ten years of papers read early will direct what you read closely.
Frequently Asked Questions
How many books are needed for PSIR optional?
Eight or nine across the four sections, plus a maintained file of current material for Indian foreign policy. It is a larger list than most optionals because the syllabus is larger.
Which is the single most useful book?
Heywood's Global Politics for Paper II Section A, and Gauba for Paper I Section A. No single book covers the subject, and any that claims to will be thin somewhere.
Is Laxmikanth enough for Indian government and politics?
No. It covers constitutional provisions and institutions but not the analytical treatment PSIR requires. Pair it with Fadia and the Oxford Companion essays.
Which comparative politics book should I use?
This is the weakest area of the available literature. Johari or Bhagwan cover the ground, and candidates should expect to supplement from Heywood and from the NCERT treatment of contemporary world politics.
Do I need all the foreign policy books?
No. Malone plus one of Sikri or Dubey is sufficient as a base. Tharoor and Dixit are readable additions rather than requirements.
How much current affairs does the subject need?
Continuous for Paper II Section B, which changes through the year. The other three sections are stable. Maintain a syllabus-mapped file rather than reading more books.
Is a political science degree required?
No. Most candidates come to the subject fresh, and the NCERT volumes exist to make the entry accessible.
Has the PSIR syllabus changed?
No change has been notified. The syllabus for both papers has been stable, and the same framework is expected in the notification of 13 January 2027.
