  3. DEFINITION OF DIGITAL LIBRARY A Public Digital Library is a collection of publications which is distributed or made available in digital form (i.e., in which the symbols are recorded as bits and bytes – magnetic, electronic, or optical). Unless otherwise qualified, the term "digital library" will be taken to mean "public digital library".

  4. SOURCES OF DIGITAL LIBRARIES • Digital files used in production of current print publications • Retrospective conversion to digital form from prior print or microform publications • Digital files with no parallel in prior print or microform publications

  5. ECONOMIC ROLES OF DIGITAL LIBRARIES • As support to decision-making and operational management • As a product, a commodity, or a basis for services • As a capital resource, an investment used for the production of other products and services

  6. GENERAL ECONOMIC PROPERTIES OF DIGITAL LIBRARIES • Easily transportable, easily and cheaply shareable • Uncertain value and time affects that value • Differences in perceptions of value, in use, in ability to use, in assessment of costs, in ability to pay costs • Value increases as size grows • Expandable and self-generating • Value independent of scale of application – indivisible in use – with great economies of scale • Cost independent of scale of application • Difficult to appropriate or to exclude access • Mixture of public good and private good • Need to balance rights of ownership and rights of use
