[p.O-1]
In operating a statewide union library catalogue project it is advisable to arrange the working periods of the “Photographers” of the Photographing Unit so that the equipment will not be idle any appreciable length of time. If only one photographing machine, employing one operator, is in service, working time requirements for the operator and the time lost in moving the machine, result in an uneconomical use of the equipment which will lie idle a considerable time in the course of a working month.
For compiling an average sized union catalogue it is recommended that two photographing machines should operate simultaneously at separate points. The additional speed of coverage will reduce the unit rental costs per machine and will result in an overall rental saving since the whole process will be more rapidly completed. In addition travel and per diem costs for the crew should be somewhat reduced. Speed in photographing is essential for the continuous occupation of the typing units which embrace the majority of project employment. For greater economy, the photographing machines each should operate 130-150 hours per month.
