Reader's Guide to J. D. Salinger Book

I picked this up at the library and read chapters that were interesting to me this afternoon. It is a decent survey, but maybe attempts to cover to broad of a time-span to be useful for much. The introductions to each excerpt tend to be about as long as the excerpt itself, which could be good or bad depending on what you are looking for. I like books like this, because they sometimes help me find whole books I want to read. There was a reader on literature of the great depression that was really good and organized like this, but I think this book would be better if it was more focused on a particular era, smaller than the 20th century.
