Truly "essential" for any letterer, whether casual or serious about the profession!
Format: Paperback
When I first got this book, I was a bit disappointed. I thought it was going to be detailing lettering by hand.
It didn't.
But guess what? It's better for it.
As the author, Nate Peikos, demonstrates, the bulk of lettering now is done digitally and with good reason. So not only is this book incredibly inspiring for any graphic artist / letterer -- with its many examples of great lettering; its demonstration of useful techniques -- the author is so open and honest in his writing. While reading it, you don't feel that he's putting the job of lettering out of the reader's reach. In fact, he's putting it right within reach through a humility that is coupled with his exceptional skills. If you're an up-and-coming letterer, someone on the outskirts of lettering wanting to delve into it more professional (like myself), or even if you've had some work doing lettering, there is something for each type in this book. It's a book that I'll cherish and reference frequently, especially with all the examples that just ooze inspiration.
My only regret is that I didn't know about some of these techniques a few years ago! But, nevertheless, I started implementing some of the techniques the first day after reading just a few pages. It reinvigorated my own desire to become a better and even semi-professional letterer, a very under-appreciated profession.

A great overall book, with one critical omission.
Format: Paperback
This is a great book to illuminate the mysterious art of comicbook lettering. It goes deep into the practical details and theory required to make a graphic novel, manga, or superhero comic with the look and feel of a professional product. But comicbook lettering is actually more than a purely aesthetic art form, it plays a critical role in conveying meaning, emotional mood, and tone of voice. Along with the artwork and panel composition, the layout of the lettering and dialogue balloons is also critical to help guide the reader's eyes naturally from panel to panel.
If you're curious about how graphic design for visual narrative works, this is an interesting and inspiring book.
My only criticism is the conspicuous omission of perhaps the one topic this author is uniquely qualified to illuminate, and that is: the actual creation of the fonts themselves. I've admired Nate's Blambot comic fonts for a long time (and have purchased licenses for some of them), so I was looking forward to at least getting an overview of how he approaches this seemingly critical aspect of comicbook lettering. But no. He doesn't go into it even slightly, which is a shame, because this would have been the perfect book on the topic if he had. I understand that font design is a huge topic unto itself, but was disappointed that in a book of this size, there weren't even a few pages dedicated to discussing the process of making fonts for comicbooks. Literally anyone reading this book would want to know that information.
Having said that, it's a great book, and I still enjoyed it very much. You'll probably be surprised by how much more there is to learn about this topic than you may have thought. Reading it will deepen your appreciation for an art form that, like a great movie score, is basically invisible when done very well, yet amplifies the emotional impact of each contributing discipline, and profoundly contributes to the enjoyment of the final experience.

Title says it all: ESSENTIAL!
Format: Paperback
This is a FANTASTIC book! The information may seem overwhelming at first, but it is easy to understand.
As some reviewers said, it does not spend much time on hand lettering (I assume this is due to the industry going more digital as time goes on). Those who want more information on hand lettering may have to seek help elsewhere. It is mentioned VERY briefly in the beginning, I believe.
It includes: step by step instructions on creating speech bubbles, tips on font creations, sentence formatting, page borders, splash/double splash page construction, creating templates that save you time in the long run, making logos, sound effects and much more.
This book is a great launching point for anyone looking to start their lettering career or even for anyone that wants to gain an appreciation for an intergral and often overlooked part of Comic books!

One of the Best "Making Comics" Books Out There
Format: Kindle
Honestly, one of the best books on making comics that I've read. So well done, insightful, well-organized, and easily referential. If you're looking for the basic principles of lettering, look no further than this.
