Please note that this is not a "700 page tome". My copy was 192 small pages, including photos and album covers.
It's a "complete guide" only in the sense of it dedicated a few paragraphs describing every album, but a book of this length can only summarize, which is exactly what I wanted anyway, being as I borrowed this from someone who told me exactly what it was. This is a cute pocket guidebook to give you a taste of what you can expect from each album.
I agree with the reviewer who said the writer seemed full of himself. Bonus smarm-points for recommending TWO of his own books in the bibliography amidst authors like Kafka, Joyce and Zappa himself. Maybe this guy is a bigger deal than I thought, but seriously? There are some strange words I had to look up, but an absolutely embarrassing amount of typos littered among them, including the gem: "If Baby Snakes was just a momento of Zappa's film of that name, Them or Us was a full-scale album." Momento.
The font used for the album titles is one of those fonts you have to take longer than you'd like to be able to accurately decipher the words, (sometimes I just read the album cover on the photo - it was easier) on account that the font uses martini glasses to represent the letter "Y", snakes to represent "L", among other weird things which look ugly and make reading difficult.
It's alright. I enjoyed it all the same. It's cute, brief, and gave me what I wanted. I liked the photos, although it would also have been even better if the album covers went along with the descriptions with them in the descriptions, and were in colour too.
I would recommend this to someone perhaps just starting out with Zappa - someone who has maybe heard and enjoyed a few albums, knows a little of what he's about, and is keen on exploring more.
