Start with books that build the language of the subject: The Oxford Handbook of Political Science, Governing the Commons: The Evolution of Institutions for Collective Action, The Globalization of World Politics, The Prince, International Relations and Non-Western Thought.
Use official and policy-focused video sources to connect theory to contemporary examples: LSE, Council on Foreign Relations, Chatham House, Foreign Affairs.
Podcasts are useful when you listen actively, pause to note the claim being made, and connect it to a course theme; good options include LSE iQ, LSE International Relations Podcasts, The Foreign Affairs Interview, CFR Podcasts, Chatham House Podcasts.
Structured courses can help you test whether the subject is still interesting when it becomes analytical rather than conversational; Introducing International Relations, International Relations, CFR Education and Global Affairs Explained as directly relevant routes into international relations and global politics.
We recommend keeping a one-page reading log with columns for claim, evidence, assumption, counterargument and course link.
