Book acknowledgements are an important part of a book as part of the elements of content. In the creative arts and scientific literature, an acknowledgement (also spelled acknowledgment in American and Canadian English) is an expression of a gratitude for assistance in creating an original work.
A book acknowledgments page includes your notes of appreciation to people who provided you with support or help during the writing process or in your writing career in general. If the information is lengthy, you may choose to put the section in the back matter before or after the bibliography. This section may also include any credits for illustrations or excerpts if not included on the copyright page.
Here the author thanks people helpful in some way relative to the book: perhaps a writing instructor, the editor at the publishing house, the author�s agent, a supportive spouse, etc. The Acknowledgements might follow the Dedication, the Table of Contents or even appear in the Back Matter, depending on the publisher�s preference.
Book design is the art of incorporating the content, style, format, design, and sequence of the various components and elements of a book into a coherent whole. The acknowledgement is usually written by the author, often part of the Preface, rather than a separate section in its own right, it acknowledges those who contributed to the creation of the book.
