Abstract: A checkbook register and account record journal system having simplified parameters by utilizing the conventional checkbook entries as an essential part of the journal. The checkbook register sheets are detachably detached along one edge only and used in the conventional manner by listing deposits and withdrawals. The checkbook register sheets are used on only one side with the reverse side preferably having an adhesive backing. The account record sheet forming the journal contains rows and columns on one side with the reverse side adapted to accept the individual checkbook register sheets. Placing the record sheets in a binder produces a complete journal with the reverse side of the record sheet containing the checkbook register sheets and the obverse side of the record sheet containing rows and columns for entering the journal entries.
