Series are various release waves of products. They are marked on the front of the box until Series Four, where the main drive of the line is instead prominent on the box.
Series may have internal sublines or "waves" (where items/availability is changed or adjusted) but dolls available remain the same along the Collector's Sheet for a full series.
