A process for serially index-marking a system of publications for filing paginated and non-paginated publications for the system comprises imprinting directly one or both faces (11, 12) of marker members (10) or imprinting a label (20) to indirectly apply the field information to a marker's face or faces. Each of the marker members having a primary field and/or at least one sub-field on at least one marker's face. The primary field (25) and sub-field (26) comprising at least one pair of readable indicia elements being mutually corresponding in each field. Each machine readable imprinted marker member for a certain publication is differentiated from other publication markers for the same publication and different publications for the system by assignment of different pairs of readable indicia to each marker member being peculiar to and representative of each marker. The pairs of indicia imprinted and carried in the fields consist of one machine readable indicia element (30) with one corresponding visually readable indicia element (30a) having a pre-determined associative relationship. The fields of indicia pairs imprinted are predetermined to appear upright to one pre-selected marker edge which extends beyond the physical edge of the respective publication (50).
