History of the Lenz-Ising Model by Stephen G. Brush might be a good one, haven't read more than a few pages of it (for a paper) myself though.
Computational Physics by Steven E. Koonin has a few pages on it.
Some percolation theory books might have a page or two on the Ising model too.
In addition, the wikipedia entry is pretty extensive if you're just looking to learn about it
Oh, as for articles, check on arXiv, I'm sure there's some papers on there about the Ising model.
