The content of this book is excellent (easily five starts). However, the electronic implementation by Logos is simply awful. I've not seen an electronic implementation of a book that is as bad as this one. Much of the Hebrew text occurs as images rather than as characters in a Hebrew font. Many of these images are unreadably small and don't change size when the text is resized. The sizing of images is inconsistent. For example, the book contains tables where some rows use images for Hebrew text while other rows have the Hebrew rendered in a Hebrew font. Moreover, the size of the images of Hebrew text can vary from row to row. The content of book is outstanding. It contains an approach to introductory Hebrew that (in my rather limited experience) is unique and very helpful. The book has helped my fledgling understanding of Biblical Hebrew in significant ways. The book has become so important to my study of Hebrew that I bought a hard copy of it. The printed version does not suffer from the deficiencies of the electronic version. The authors of this book deserve much better than the mess Logos has made of their work. Kurtz and Josberger have made an important contribution. The Logos implementation of their good work does not reflect the value of it. I highly recommend buying this the print version book.
