  • Great information. Our library has done some newspaper digitization, via a 3rd party vendor. Now thinking of digitizing a collection of photos and artifacts. Need all the information one can gather.

    4. 4. What is a Digital Library?
    5. 5. Define: Digital Library “ Digital libraries are organizations that provide the resources, including specialized staff, to select, structure, offer intellectual access to, interpret, distribute, preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities.” Digital Library Federation Annual Report ,(1998-1999) 1.
    6. 6. Components “ Digital libraries are organizations that provide the resources , including specialized staff , to select , structure , offer intellectual access to, interpret , distribute , preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities.” Digital Library Federation Annual Report ,(1998-1999) 1.
    7. 7. Digitization ≠ Preservation

    55. 65. Deciding on a scheme It is very important to decide what the material is, what needs to be described, who it is intended for, how it will be retrieved, and how it will be processed and used before deciding on a scheme for its description. - Dr. Peter Noerr Digital Library Toolkit – Sun Microsystems
