A "Galley Proof" is a preliminary version of a printed work, typically used in the publishing process. It is created after the manuscript has been typeset but before the final printing. This proof allows authors, editors, and publishers to review the text for errors, formatting issues, and overall layout. Galley proofs are often printed on large sheets of paper, which are then folded to create pages. This stage is crucial for ensuring that the final product, such as a book or magazine, is polished and free of mistakes. Corrections made during this phase can significantly improve the quality of the finished work.
