Laura Most definitely yes. As someone who loves Tolkein and has read everything he has written, I would argue he didn't write enough! However, the actual Lord of the Rings series is just the three books with the one prequel, The Hobbit. The other books are in the same universe, but aren't in the same time period/story arc as The Hobbit and the LOTR. I'd recommend reading The Hobbit, and, if you like it, trying The Fellowship of the Ring.
