I agree with the last comment, Book can be interesting but today your research needs to be published as papers in ranked journals to have an impact, I think.
Yes, you can convert your dissertation into a book.
How to go about it include:
1. Identify your audience. This will strongly influence how you organize and write your book, differentiating it from your dissertation; because, the purpose of a dissertation is to show that you're knowledgeable about your field of study and have made a significant contribution to it. While the purpose of a book is to serve a need for the reader.
2. Identify competing books, so as to determine how your book will fill a gap for the audience.
3. Create an outline for your book as you begin with the major topic for each chapter and thinking about how the overall theme will progress through the entire book.
4. Write a sample chapter.
5. Identify appropriate publisher and learn the publishing landscape in your field by:
i. Getting a sense of how editors will review your book.
ii. Review your bookshelf and bibliography.
iii. Close read press website to ensure your target presses publish books like yours.
iv. Reach out to authors who have recently published books at your target press and learn valuable information about their timeline and experiences.
v. Open up informal or formal conversations with editors about your project.
a PUBLISHED BOOK IN SOME ACADEMIC DEPARTMENTS IS WORTH MORE THAN TWO PLUS ARTICLES. tHAT SAID, IF YOU CAN SOMEHOW WRANGLE AN ARTICLE OR TWO RELATED TO THE DISSERTATION WITHOUT SPOILING THE BOOK PUBLICATION THAT IS IDEAL. iN ANY CASE, DEPENDING ON YOUR DISSERTATION TOPIC YOU SHOULD TRY SEVERAL PUBLISHERS THAT PRINT IN THAT FIELD. if YOU HAVE A PROMINENT PROFESSOR WHO CAN HELP YOU OR UNIVERSITY pRESS TRY THAT ROUTE ALSO.. gOOD LUCK!
