A NEW l&EC FEATURE Beginning with the January 1957 issue, the Workbook pages (Anumbered pages) have been perforated. This new approach was adopted by the editors to increase the usefulness of these pages to the reader. In a test of this operation for the editors, more than 9 0 % of the readers endorsed it.
