Some 1120 Recommendations from the Blue Book are still in force. 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.
