The term \u201cgalley proof\u201d comes from a time before electronic media, computers, and even typewriters, when type was actually hand set using wooden or metal blocks and placed into metal trays called \u201cgalleys.\u201d These were then used to print single-column pages of type, or \u201cproofs,\u201d that the authors would check for any needed corrections to the text and send back to the printer. The printer would then painstakingly rearrange the blocks of type that needed to be corrected before printing again. What a time-consuming endeavor! Of course, now that everything is electronic, this process is simplified and less time-consuming, but the final manuscript text is still not published until there is one more author review, and hence the term \u201cgalley proof\u201d is still used today.<\/p>\n
