They are included in fascicles and volumes of the Blue Book that may still be purchased from the ITU Sales Service. Since the beginning of the 1988-1993 Study Period ("post Blue Book") ITU-T Recommendations are published and offered for sale individually (in separate fascicles). The price of each fascicle, based on the number of pages, is provided for individually published Recommendations in the Table below. ---------------------------------------------------------------------- Number of Pages Administrations (ITU) Other Subscribers ---------------------------------------------------------------------- up to 8 Fr.S. 7.- Fr.s. 8.- from 9 to 16 Fr.S. 10.- Fr.s. 11.- from 17 to 32 Fr.S. 14.- Fr.s. 15.- from 33 to 48 Fr.S. 18.- Fr.s. 20.- from 49 to 64 Fr.S. 22.- Fr.s. 24.- from 65 to 80 Fr.S. 26.- Fr.s. 29.- from 81 to 96 Fr.S. 30.- Fr.s. 33.- from 97 to 112 Fr.S. 34.- Fr.s. 38.- from 113 to 128 Fr.S. 38.- Fr.s. 42.- from 129 to 144 Fr.S. 42.- Fr.s. 47.- from 145 to 160 Fr.S. 46.- Fr.s. 51.- from 161 to 200 Fr.S. 56.- Fr.s. 61.- from 201 to 300 Fr.S. 69.- Fr.s. 75.- from 301 to 400 Fr.S. 85.- Fr.s. 93.- ---------------------------------------------------------------------- For the Blue Book publications, please retrieve from the TAM, the document "List of ITU Publications" with UPI ITU-3025. ---------------------------------------------------------------------- How to order ITU-T Recommendations Catalogue General conditions Since all orders are payable in advance, amounts due should be sent in Swiss francs at the same time as the order.
