Sure! Here are a couple of books that discuss some of the history of liberalism and its wrongdoings:

One's I've read:

• Domenico Losurdo's Stalin: The History and Critique of a Black Legend (this has sections that describe the genocidal history of liberalism. You don't have to like Stalin to read this, and if you want just skip to the parts about liberalism's history)
• Naomi Klein's The Shock Doctrine: The Rise of Disaster Capitalism
• Thomas Frank's Listen, Liberal: Or, What Ever Happened to the Party of the People? (this is a more US-centric book that talks about liberalism's shortcomings in the US rather than its genocidal wrongdoings. I'm assuming you're from the US.)

Ones I haven't read:

• Domenico Losurdo's Liberalism: A Counter-History
• William Blum's Killing Hope

For a starting point in learning about Marxism, I'll point you to a comment I made the other day. I very very highly recommend reading anything in these lists that discusses historical or dialectical materialism, including Georges Politzer's Elementary Principles of Philosophy. Dialectical materialism is the tool Marxists use to analyze the world. Marxism without a good understanding of dialectical materialism won't do you any good. Huey Newton said as much in his autobiography Revolutionary Suicide, so I think more importance needs to be placed in teaching newcomers dialectical materialism.

On the topic of Huey Newton, I think reading about his life and the life of all other black revolutionaries is incredibly important to understand liberalism's wrongdoings. They all had to live through those wrongdoings and were able to understand them well.

Finally, just read philosophy in general. It's fun, it helps you see the world in new ways, and it's just mentally stimulating.

Huey Newton on his journey learning philosophy in college and how he incorporated it into his revolutionary programs:

I was also impressed with A. J. Ayer’s logical positivism, particularly his distinction between three kinds of statements—the analytical statement, the synthetic statement, and statements of assumption. These ideas have helped me to develop my own thinking and ideology. Ayer once stated, “Nothing can be real if it cannot be conceptualized, articulated, and shared.” That notion stuck with me and became very important when I began to use the ideological method of dialectical materialism as a world view. The ideology of the Black Panthers stands on that premise and proceeds on that basis, to conceptualize, articulate, and share. Some key aspects of Black Panther ideology and rhetoric, like “All Power to the People” and the concept “pig,” developed out of that. They were not haphazardly introduced into our thinking or vocabulary.
