A mail sorter made up of a plurality of identical leaves each coded to one or more addresses with a flexible and expandable bellows binding joining the leaves into a book whereby the leaves may be arranged on a flat surface in staggered, stair step, offset fashion for sorting of mail by insertion of individual mail pieces between the leaves, whereupon the leaves may be gathered into superposed relationship and turned to a vertical orientation with the mail between the leaves, whereupon the resultant neat stack of sorted, superposed mail pieces may be easily removed from the mail sorter book. Identical, aligned apertures may be formed through the leaves to facilitate removal of sorted mail from the book, as by insertion of a pencil or the like through the apertures and movement of the pencil, against the sorted mail, towards the open end of the mail sorter book. Each leaf of the book may be multiply coded in sets of indicia, so that a single sorter may be used to repetitively sort mail by address, for a number of streets, buildings, etc. Both faces of each leaf may be coded.
