What are some new, instant, or probable "classics" from 1995 to 2017?

Do you have favourite books or papers you'd consider to be or become "classics" from the last 20 years?

EDIT: Great answers here, thanks everybody! Follow-up question: Do you also have more recommendations from outside the Anglo-Saxon sphere of philosophy? What about Skandinavian, German, Italian, Russian… thinkers? What about Africans and South-Americans?

In Political Philosophy:

Books

- *Multicultural Citizenship* by Will Kymlicka: Perhaps the most important publication to come out of the liberalism versus communitarianism debate, it has largely defined the liberal approach to issues of culture, nationality, and ethnic identity. Widely cited across multiple disciplines which is somewhat rare for a contemporary piece of political philosophy.

- *Rescuing Justice and Equality* by G.A.Cohen: Arguably Cohen's Magnum Opus, this book is probably the most rigorous left-wing critique of Rawlsian liberalism. It has become a foundational text in modern debates regarding the methodology of analytic political philosophy (especially the debate over ideal theory).  

- *National Responsibility and Global Justice* by David Miller: A seminal text in the Global Justice literature, Miller provides a comprehensive, lucid, and intellectually rigorous statist/nationalist alternative to the dominant cosmopolitan paradigm. 

Articles

- *Justice in Migration: A Closed Borders Utopia* by Lea Ypi: Ypi completely breaks through the traditional dichotomy in debates about the ethics of migration by proposing that the relevant principles of justice must consider both the effects of immigration and emigration. In doing so, she turns our attention towards the vastly under-theorized idea of justice in emigration and pushes against the received wisdom that emigration ought to always be permissible.   

- *What is the point of Equality?* by Elizabeth Anderson: A massively impressive article both in terms of originality and scope. Anderson successfully challenges some of the most influential conceptions of egalitarianism (including luck egalitarianism) and sheds a lot of light on one of the central concepts of contemporary political philosophy.

- *The roles of religious conviction in a publicly justified polity: The implications of convergence, asymmetry and political institutions.*
by Gerald Gaus and Kevin Vallier: A central work in the emergent  literature on post-rawlsian public reason, Gaus and Vallier challenges the dominant "consensus" model of public justification. In its place, they offer a now highly influential "convergence" account which they see as better able to deal with the facts of persistent disagreement in society.
