I bought this book as a study aid in my russian language class. The information is thorough and very helpful - including examples of how the verbs are used in sentences. Were I reviewing a paper edition, I would most likely give it 4 or 5 stars. Unfortunately, the formatting of the kindle edition has a quite negative effect on the use of the book. all (or at least most) of the Russian text appears to be in image files. as such, it does not scale with the rest of the text in the book, and can be difficult to read at times, not to mention the fact that the images greatly increase the size of the book. I assume the reasons the publisher did this is because 1) of the placement of most of the verb information in tables and 2) the non-latin letters (due to the fact that Russian text not in tables is also in images). I must confess, I am greatly confused as to *why* a professional publishing house like McGraw-Hill has done this, considering the fact that I (essentially an amateur in the realm of ebooks), in the course of making electronic versions of portions of my class notes for easy portability, have made ebooks containing both tables and Cyrillic characters with very little difficulty that are perfectly readable on my kindle. I've come across the use of images instead of tables in many electronic editions of books, particularly textbooks and similar, and I cannot understand why the publishing industry does not take full advantage of the options available to them. The only two possibilities that spring immediately to mind are that they somehow aren't aware of all that can be done in ebooks, or that amazon doesn't allow it for some reason, both of which seem to me a rather unlikely crippling of one's own product.
