Starting out • Contemplating a digital conversion project? • Is the added value worth the price? • Added value: • Enhanced intellectual control • Increased and enriched use • Encouragement of new scholarly use • Creation of a virtual collection
Digital Technology promisesto… • Extentthereachofresearchandeducation • Improvethequalityoflearning • Reshapescholarlycommunication. Digital conversionoflibraryholdingscanbroadenaccesstovaluable but scarceresources. The costofconversionis high.
The dream of the virtual library comes forward now not because it promises an exciting future, but because it promises a future that will be just like the past, only better and faster. -James J. O‘Donnell, Avatars of the World
Good digital collections • Expicitcollection-developmentpolicy • Providing a description, Metadata • Sustainabiltyover time (also beyondthefundedperiod) • Broadavailabilty & avoidanceofunnecessaryimpedimentstouse • Respectingintellectualpropertyrights • Providing measurmentofuse • Fitting into a larger contextof digital library initiatives
Good digital objects • Support collection priorities • Are persistent • Remain accessible over time despite changing technologies • Are exchangeable across platforms, broadly accessible • Have a persistent, unique identifier
Can be authenticated in at least two senses: • Object‘s origins, structure, and developmental history • A user should be alble to determine that the object is what is purports to be. • Will have metadata. • Descriptive and administrative
Good metadata… • Is appropriate • Supports interoperability • Uses standard controlled vocabularies • Inludes a clear statement on conditions and terms of use • Has the qualities of good objects: achivability, persistence, unique identification… • Supports long-term management of objects
A good digitization project… • Has a substantial design component • Has an evaluation plan • Produces a project report
„Digital“ is a kind of genus term for all things composed of ones and zeros.
Digitization for preservation • Ideally, the formats would be based on open and well-documented standards. • Digital-preservation formats may be different from the file formats that the library delivers directly to users. • TIFF, JPG, GIF
Digitization for discovery • OCR is of utmost importance • Machine-readable form of text-documents • Sound and video discovery are highly desired but not yet at a marketable stage in their developement.
Digitization for delivery • Digital files are ideal delivery formats. • For nontextual media, there are alternatives. • Online streaming allows individual users to receive and experience content.
Digitization for reading • Goal ofdigitzingforreadingistoproduce a viablereadingexperience in the digital format. • Characteristicsofpaperbooksshouldbeimplemented • Numberedpages • Bookmarking • Navigation to individual pagesorchapters • Digital filesdesignedforextendedreadingneedtobe portable.
In the digital library, users# experiences will be degraded if their expextations of digital library materials do not meet the actual capabilities.
Starting a digitization project • Purpose, benefitsofhavingtheparticularcollection in digital form? • Goals ofproject? • Isthemaingoalincreasedaccesordecreasedhandlingof fragile originals? Orboth? • Will digital imagesreplaceorsupplementexistingoriginals? • Will theycomplementexistingcollectionsor will theyfill a lack ofdigitizedmaterials?
Who is your audience? • What are the physical characteristics of the collection? • Who owns it? • What is your time frame? • How is the project being funded? • Who will be responsible at different stages of the project
How will you perform the actual digitization? • What metadata scheme are you planning to use? • How are you going to provide access to the collection? • How will you maintain the collection into the future?
Technical infrastrucutre/ imagecreation • Is this scanner compatible with my documents? • Can this scanne produce the requisite quality to meet my needs? • Can this scanner support my production schedule and conversion budget?

It becomes critical for libraries to understand the current technological landscape and to have an articulate vision of the customers they intend to serve. Without this clarity, technology – rather than vision and needs – may end up drinving change.
By considering the end user‘s point of view, libraries can better shape technology systems and define their own service offerings more clearly.
