This volume lists EVERY verb in the Hebrew Bible (the Old Testament) by book and by verse. The text used for this study is Biblia Hebraica Stuttgartensia(BHS), which is based on the Leningrad Codex. As such the book is a valuable tool for research and reference. There are software tools available nowadays, but generally speaking these are quite expensive. This book is certainly a good alternative, depending on the scope of study and the need.
Besides the usual table of contents, brief introduction and a list of abbreviations, all there is to the book is a long list of verbs. All 689 pages of them, listed in two columns per page. They are listed by the book, chapter and verse, the book order follows Holy Bible: King James Version (KJV) ordering. After listing the reference, the actual verb form in Hebrew is listed, followed by stem, tense, person/gender/number, root, suffix (if any), BDB page number (Brown-Driver-Briggs Hebrew and English Lexicon), KB page number (Koehler-Baumgartner's The Hebrew and Aramaic Lexicon of the Old Testament, 2 volume set), and meaning. This is pretty much all you need when working with Hebrew verbs.
I'll repeat the same caution noted in my review of Davidson's The Analytical Hebrew and Chaldee Lexicon, that this work isn't intended and shouldn't be used while reading the Hebrew text. If you're a beginning student, it could become too much of a crutch if you're not careful and actually hurt your ability to learn Hebrew. Perhaps you could use it to validate your parsing exercise once you've completed it or do word study, but avoid looking up works as you read. Doing so will make you be reliant on the book and not on your own skills and understanding of the language, grammar and syntax. I use this for work and syntactical studies, for example looking at the tense, mood, etc. used in a particular discourse, prophetic book (in case of minor prophets) or the like.
