This is the newest edition of a very popular manual which is used in classrooms around the world to assist students learning to read the Hebrew Bible.
Upon careful reading, I found the explanation of the accents in this volume to be adequate, especially when applied directly to individual verses in the BHS.
After giving some specific information on certain common disjunctive accents, it then shows the rest of the disjunctive accents with little or no explanation as to what they are doing in the text. The conjunctive accents are listed separately with no explanation whatsoever as to how they work. And two of the most common text pointings found in the Hebrew Bible are missing! I've never found memorizing symbols without explanations to be of any help in anything.
One should just pay a little more money and buy a reference which gives all the accents and explains their uses. As it is, my copy of this book has told me virtually nothing that I hadn't already learned in the two Hebrew grammars/ workbooks I've used to learn Hebrew.
Invest your money elsewhere than in this book.
