Scrutinize your manuscript, and make note of its significant points. Draft a rough synopsis, or brief description, of the manuscript, referring to your notes if necessary. After editing the rough draft, you should have a nice polished synopsis. Set this synopsis aside to use later as the second paragraph of your query letter.
Review your resume. Circle the areas that could be included in the query letter. Underscore publication credits and literary awards. Include any pertinent experience, past or current, that relates to the book project. Using this information, write a brief paragraph that highlights your accomplishments. Edit carefully and correct any errors. This accomplishments paragraph will represent the final detail of your query, so prepare this statement as concluding information.
Outline any marketing strategies, including use of social media and web platforms. For example, explain if you have a well-publicized blog or e-newsletter, or cite the number of followers on a social website. Research the agent or editor thoroughly. Be prepared to include knowledge of his specialty and literary trends and why and how your project relates. Craft this information into a marketing statement.
Format your query letter using a business model. Use 12-point Times Roman type, and double-space. Position the recipient's name, title and business address in the upper left of the letter. The date goes above the name. One-page query letters are preferred over lengthy narratives spanning several pages.
Address the recipient formally. For example, "Dear Mr. Smith" would be an appropriate salutation. Then begin the body of the letter by briefly explaining why the query is being submitted. Include the title of your manuscript, genre, target market and number of words.
Begin the second paragraph with your polished synopsis. A synopsis should be exciting enough to "hook" the recipient and make him want to read more.
In the third and final paragraph, state why the project is meaningful. Explain the manuscript's potential universality and commercial appeal using the marketing statement you put together. Conclude this section with your accomplishments statement.
End the letter with "Thank you for considering my work." You may also include "I look forward to hearing from you soon."
