Abstract
An improved corrective lens for copying pages of a book pressed flat upon a document support glass of a xerographic copying machine or document scanner. The corrective lens is shaped to fit in the space between the book pages to be copied and the document glass of the copier. The corrective lens has a pyramidal center extending into the crease of a typical book. The lens extends outwardly from the pyramidal center to form substantially flat side portions that hold the pages of the open book in place.
