A great new grammar book, "The Essentials of English Grammar in 90 Minutes" by Prof. Robert Hollander [Dover, $4.95] bridges the gap between basic grammar books (for both children and adults) and higher-level books such as the recommended "Essential English Grammar" by Philip Gucker, also from Dover Publications. This is in a read-only format -- almost no quizzes or charts, etc. but will give you an over-all picture of not only basic, but higher level grammar. Please see my Amazon Review of this nice little addition to the grammar teacher's and learner's bookshelf.
