A manuscript copy edit for a children's picture book would include:
 
Language and Grammar Correction of spelling errors, punctuation mistakes, grammar issues, and sentence structure problems. This includes ensuring consistent verb tenses throughout the story and proper capitalization.
 
Style and Consistency Checking that character names, locations, and descriptive details remain consistent throughout the manuscript. The editor ensures the writing style matches the intended age group and maintains a consistent voice and tone.
 
Clarity and Flow Improving sentence clarity, eliminating awkward phrasing, and ensuring smooth transitions between scenes or pages. This includes identifying and fixing confusing or ambiguous passages that might puzzle young readers.
 
Word Choice and Language Level Ensuring vocabulary is appropriate for the target age group, replacing overly complex words with simpler alternatives when needed, and maintaining engaging, child-friendly language throughout.
 
Dialogue and Character Voice Refining dialogue to sound natural and age-appropriate, ensuring each character has a distinct voice, and checking that conversations flow realistically.
 
Technical Elements Formatting consistency, proper paragraph breaks, correct use of italics or emphasis, and ensuring any special text elements (like sound effects or repeated phrases) are clearly marked.
 
Pacing and Rhythm Since picture books are often read aloud, the copy editor pays attention to how the text flows when spoken, identifying tongue twisters or awkward rhythms that might disrupt the reading experience.
 
A copy edit focuses on the text itself rather than broader story structure issues, which would be addressed in a developmental edit. Turnaround time 3-4 weeks.
