Digital libraries, value, and productivity

A digital library is popularly viewed an electronic version of a public library. But replacing paper by electronic storage leads to three major differences: storage in digital form, direct communication to obtain material, and copying from a master version. These differences in turn lead to a plethora of further differences, so that eventually the digital library no longer mimics the traditional library. Furthermore, a library is only element in the process of creating, storing, culling, accessing, selecting, and distributing information to customers. While the technical focus of digital library research is on the central functions of storage and access, major changes will occur in the interaction within the new systems.
