The relation between ANOVA and regression goes to the heart of the linear model; they are, at once, both inter-connected aspects of the linear model. In fact, one could interpret ANOVA as regression on indicator variables. If you want to go further, one could contrast linear modeling ingeneral with experimental design as well. Again, both are inter-connected. This perspective is outlined well in the Kutner, Neter, & Wasserman books on linear models. There there are 2 or 3 versions on the market, in various editions. The current one is called "Applied Linear Statistical Models". A more theoretical approach can be found in Searle's Linear Models. No false placebo effect here !
