ABSTRACT:
An enlarged print book is produced by microfilming the front and back pages of each sheet of an original book, printing each of such pages from the microfilm at a desired page size, severing each printed page approximately in half, arranging the bottom half of one page above the top half of a succeeding page with the severed upper end or trim line of the bottom half a predetermined distance above the severed lower end or trim line of the top of the succeeding page, microfilming such arrangement on a single film frame, enlarging the single frame to a predetermined extent to produce a single enlarged sheet having the bottom half at its top and top half at its bottom, trimming the top and bottom halves at exactly their respective upper and lower trim lines, folding each enlarged sheet precisely midway between their trim lines with the printed sides of the bottom and top halves exposed, producing each succeeding enlarged sheet from the original book in the above manner, and binding successive enlarged sheets together at their trim lines to produce a finished book, whereby opening of the book will expose the enlarged top half of a page of the original book above the enlarged bottom half of the same page of the original book.
