Besides the obvious: Experience in a technical field...What is the process for becoming an author of a technical book? When during the writing process should you contact a publisher? How do you know which publisher to contact? I have been thinking about writing an introductory engineering book for high school to entry level college students. Something as a primer for getting your feet wet in engineering, before spending $30k+ on college courses. I have an outline, and plan to spend the next two years writing. (Probably take longer, but I am an optimist) I am looking for about 400 pages and I am hoping the book will retail for about 60-75 dollars. My main market would be high school technology instructors and professors of engineering design courses. How much and how does an author get paid for a book? Is there any up-front cost to publish? How do I get the book reviewed before / after publishing? I am thinking about paying some of my college professors to reveiw the book for me. Any information would be appreciated.
