Buy a copy of Kittel and read it? His superconductivity chapter is okay enough and only like 50 pages. I know that's not too helpful, but it's hard to offer much of anything if you don't share what you're struggling with. Or, if you're looking for a Wikipedia-level introduction, I'd suggest... Well, Wikipedia.
