Someone wrote a book by this name. The Abarbanel on לא תשא עליו חטא explains that when admonishing someone, don’t put the sin on him, don’t call him names, but say that his actions or behavior is bad. This he can change but he can’t change himself. Also, put yourself in his place אל תדין את חבירך עד שתגיע למקומו.
I saw an interpretation ( don’t recall who said it) that one shouldn’t put, or carry לא תשא עליו , his own sin on his fellow Jew unless he’s free of it himself.
הוכיח חכם ויאהבך the Shlah Hakadosh says that when you admonish someone don’t call him a letz because he will end up to hate you, but if you call him a chacham, he will love you.
