New Oxford Review is a solidly orthodox Catholic online magazine. I’m not saying that I agree with the contents of every article. Faithful Catholics can and should at times disagree on matters that are not essential to the Faith. And the articles are written by a wide range of different authors. But the articles are typically insightful, theologically-sound, and they have a depth of understanding on various topics that is greater than many other online sources.
I also find their daily summary of Catholic new stories, in the right column of their front page, to be a useful starting point. It helps me to stay informed about issues in the news of concern to Catholics.
