dc.description.abstract For many institutions, outsourcing is the most practical way to carry out map digitization projects. High-resolution images of large maps cannot be obtained using the equipment available in most libraries, such as desktop scanners and ordinary digital cameras. Top quality high-resolution scanning of large maps requires such expensive equipment as digital view camera backs, oversized flatbed scanners, or specialized drum scanners. Only the largest institutions have the budget and support staff to be able to employ such equipment. Except for very large libraries with thousands of maps to digitize, outsourcing is the only alternative. And, given the rapid obsolesence of scanning equipment and the need for trained technicians, even the largest research libraries have outsourced map digitization projects. Anyone working with a service provider should be prepared to ask a number of questions, and to draw up a contract specifying exactly what is expected. It is always a good idea to ask vendors for references. A few things to consider: What is the cost per item? At what resolution will the maps be scanned? What type of image files will be provided? How will the scanned images be stored? What metadata, if any, will be provided? If some of the maps are to be scanned through mylar, what will be done to minimize reflections? How important is total color fidelity in mages of maps? What equipment will be used for scanning? In particular, attention should be paid to the pros and cons of using high-end digital cameras versus flatbed and sheet-feed scanners. This page concludes with a short bibliography of articles on digital imaging issues, which should provide readers with the necessary background information for working with vendors. en_US
