von Eye, Alexander, and Eun Young Mun. Rater Agreement: Manifest Variable Methods. Mahwah, NJ: Lawrence Erlbaum, 2005.
From the publisher's description: "This book is intended to help researchers statistically examine rater agreement by reviewing four different approaches to the technique... The first approach introduces readers to calculating coefficients that allow one to summarize agreements in a single score. The second approach involves estimating log-linear models that allow one to test specific hypotheses about the structure of a cross-classification of two or more raters' judgments. The third approach explores cross-classifications or raters' agreement for indicators of agreement or disagreement, and for indicators of such characteristics as trends. The fourth approach compares the correlation or covariation structures of variables that raters use to describe objects, behaviors, or individuals. These structures can be compared for two or more raters."
