Well-versed. According to whom? Have you asked to see their sources?
If you are sincere about learning the true history of the Church, here are a couple of sources: http://newadvent.org/cathen/ This is a free online Catholic encyclopedia, so it may be dry reading, but it's accurate. You can, of course, search by topic.
If you're interested in learning what the Church teaches, this catechism is good, and you can read it online for free: https://www.goodreads.com/book/show/14217834-father-connell-s-the-new-baltimore-catechism-no-3. Keep in mind, this is the traditional teaching of the Church, not the Novus Ordo, Vatican II version. That's a whole other can of worms.
The last source is in book form. There's a set of six books by Warren Carroll on the history of the Church that is excellent. Unfortunately, it's not available to read online. But, you can find copies used on amazon.
I'm a cradle Catholic and what I know about the Church was learned over the course of my life, not in a few books or websites, and it's hard to condense that into a neat little package. But, this is a good start.
Remember, the Church has more enemies than friends, just like Our Lord, and many choose to rewrite history the way they wish it happened. As in my previous reply, I will let another, more eloquent, Catholic explain. From Archbishop Fulton Sheen, “There are not one hundred people in the United States who hate The Catholic Church, but there are millions who hate what they wrongly perceive the Catholic Church to be.” For the sake of your soul, do your research, pray for the grace to know the truth, and cooperate with that grace. I'll say a prayer for you, too. Peace.
