  receipt by the prisoners of relief supplies. Books may not be included in parcels of clothing and
  foodstuffs. Medical supplies shall, as a rule, be sent in collective parcels.
  ARTICLE 73
  In the absence of special agreements between the Powers concerned on the conditions for the
  receipt and distribution of collective relief shipments, the rules and regulations concerning
  collective shipments, which are annexed to the present Convention, shall be applied.
  The special agreements referred to above shall in no case restrict the right of prisoners'
  representatives to take possession of collective relief shipments intended for prisoners of war, to
  proceed to their distribution or to dispose of them in the interest of the prisoners.
  Nor shall such agreements restrict the right of representatives of the Protecting Power, the
  International Committee of the Red Cross or any other organization giving assistance to
  prisoners of war and responsible for the forwarding of collective shipments, to supervise their
  distribution to the recipients.
  ARTICLE 74
  All relief shipments for prisoners of war shall be exempt from import, customs and other dues.
  Correspondence, relief shipments and authorized remittances of money addressed to prisoners of
  war or dispatched by them through the post office, either direct or through the Information
  Bureau provided for in Article 122 and the Central Prisoners of War Agency provided for in
  Article 123, shall be exempt from any postal dues, both in the countries of origin and destination,
  and in intermediate countries.
  If relief shipments intended for prisoners of war cannot be sent through the post office by reason
  of weight or for any other cause, the cost of transportation shall be borne by the Detaining Power
  in all the territories under its control. The other Powers party to the Convention shall bear the
  cost of transport in their respective territories.
  In the absence of special agreements between the Parties concerned, the costs connected with
  transport of such shipments, other than costs covered by the above exemption, shall be charged
  to the senders.
  The High Contracting Parties shall endeavor to reduce, so far as possible, the rates charged for
  telegrams sent by prisoners of war, or addressed to them.
  ARTICLE 75
  Should military operations prevent the Powers concerned from fulfilling their obligation to
  assure the transport of the shipments referred to in Articles 70, 71, 72 and 77, the Protecting
  Powers concerned, the International Committee of the Red Cross or any other organization duly
  approved by the Parties to the conflict may undertake to ensure the conveyance of such
  shipments by suitable means (railway wagons, motor vehicles, vessels or aircraft, etc.). For this
  purpose, the High Contracting Parties shall endeavor to supply them with such transport and to
  allow its circulation, especially by granting the necessary safe-conducts.
