Title: Very good
Review: OK, it's not perfect. It is, however, a good book, better than most textbooks, and way, way ahead of Berlitz, for learning Spanish. Most Americans think they can learn a language in like 2-3 weeks. This is not so. It takes consistent practice to learn a language. This book supports that rather well. I'm sure the author is long gone, however, the book lives on. It is cited in The Next Whole Earth Catalog, by way, which is why I got my first copy of it.
