The editors recently received telefacsimile cost data for several academic institutions. The cost per page-—for interstate transmission——was $.10 to $.18, with the average being $.14. One institution consciously sought to reduce what had been their average cost of $.135 per page by delaying transmission until the hours of 10:00 P.M. to 8:00 A.M. The average cost dropped to $.072 per page. Unquestionably, transmitting when the rates are lowest is the biggest single factor in reducing telefacsimile costs. In the case of the library which made the adjustment, the savings may be as great as $96.00 per month for the 1,600 pages it sends. Any library which expects to send more than 1,000 pages a month should seriously consider a machine with delayed transmission capability, or should have a staff member come in at 7:00 A.M. to initiate transmission before the rates change.
