The artist of my book is Stephen J. Eskilson, who has produced Graphic Design: A New History as a predecessor to his revision, Graphic Design: A History. This book was produced as an academic tour of graphic design from the past hundred years. Eskilson has not produced any other books which suggests he is not only a scholar but an actual designer as his main profession. The book was created to be a referencing tool for undergraduate students in order to create informed theory work all inside one book. The publisher of the book is Laurence King, a publisher known in the creative industry as they mainly publish books in the arts. They are a well-known and respected publisher, so Stephen must be a knowledgable figure in the creative industry. They have also published books by authors such as Pentagram, which are quite influential.
The purpose of the book is mainly to cater to undergraduate students and to create an in-depth recollection of graphic design from the past hundred years. This could be used for either teachers to use as a guideline of chronological events in graphic design, or for undergraduates themselves to catch themselves up on major events and use the book as a referencing tool. The text heavy aspect of this book suggests it's not meant to be viewed more as an aesthetically pleasing piece of art more than the communication aspect it holds.
The ethos followed within the book is hard to identify due to the literal storytelling in the book, but I think the author intended to make an un-biased recollection of events, meaning his ethos wasn't a prominent factor in the creation.
The classification of the book is 741.605 which I think is the category of the history of graphic design. Here is a screenshot of what other books are in the classification in the library. As you can see they all refer to past graphic design instead of contemporary or future graphic design. The books are all information based and all sound text-based as opposed to image based which also back up my claim that most of these books are forms of referencing tools.
