Abstract: A cheque book assembly comprises carrier leaves arranged one above another and bound together at their right hand ends. Cheques making up a sub-set are bound detachably to each carrier leaf at their left hand ends with a staggered overlap between the cheques. A pressure sensitive strip causes an inscription on an elongated field of a first cheque to be reproduced on a corresponding field on the first carrier leaf to provide a journal entry for the first cheque. Other pressure sensitive strips cause inscriptions on the other cheques to be reproduced on other fields of the carrier leaf, these fields being offset from one another by the stagger of the cheques to form a journal for the sub-set of cheques.
