They brazenly used nail files to remove items from scrapbooks, or as they referred to it, "perform surgery," court documents said. In some cases, they removed inventory markings "by applying sandpaper and other abrasive materials to the document," the documents said.

Several thousand documents still remain in gray boxes on shelves at the National Archives in College Park, waiting to be returned.
