After the iPad and the wireless barcode scanner were introduced to the workflow,
I no longer needed to haul new books to the printer room and to the processing room.
Scanning can now be done wherever the new books are located.
I also no longer need to occupy or take the scanner/copier away from our students.
Most importantly, I no longer need to revise subject line or supply location and material-type notes in a separate step.
The iPad serves both as an image scanner and a PC in this case.
