3What is Library Characteristics Collection of books, documents, newspapers, audio visual materials kept and organized for people to read or borrow.CharacteristicsCollection of data objectsCollection of Metadata StructuresCollection of ServicesDomain FocusQuality ControlPreservation
4Definitions Digital Library Hybrid Library Virtual Library Collection of electronic resources that provides direct/indirect access to a systematically organized collection of digital objects.Hybrid LibraryProvides services in a mixed-mode, electronic and paper, environment, particularly in a co-coordinated way. Derived from a strand of eLib which explored the issues surrounding the retrieval and delivery of information in these types of environment but also investigated the integration of different electronic services so that single search approach could be offered to the End user.Virtual LibraryAccess to electronic information in a variety of remote locations through a local online catalogue or other gateway, such as the internet

13Types of Digital Libraries Stand-alone Digital Library (SDL)Federated Digital Library (FDL)Harvested Digital Library (HDL)
14Stand-alone Digital Library (SDL) This is the regular classical library implemented in a fully computerized fashion. SDL is simply a library in which the holdings are digital (scanned or digitized). The SDL is self-contained - the material is localized and centralized.
17Federated Digital Library (FDL) This is a federation of several independent SDLs in the network, organized around a common theme, and coupled together on the network. A FDL composes several autonomous SDLs that form a networked library with a transparent user interface. The different SDLs are heterogeneous and are connected via communication networks.

22Harvested Digital Library (HDL) This is a virtual library providing summarized access to related material scattered over the network. . Examples of HDLs are the Internet Public Library (IPL)A HDL holds only metadata with pointers to the holdings that are "one click away" in Cyberspace.Developed by Library Professionals, or Computer Scientists
23Four Corner Stones of Digital Library Communication technologiesCommunityContentComputer

33Myths The internet is the digital library Fully automated library is digital libraryThe myth of a single digital library or one-window view of digital library collectionsDigital libraries will provide more equitable access, anywhere, any timeDigital libraries will be cheaper than print libraries
34ChallengesInteroperability Technical, process, language, ( Different platforms etc)Building digital collections2.a Digitization2.b Acquisition of original digital works2.c Access to external materialsMetadataNaming, identifiers, and persistence 4.a Uniform Resource Locator (URL) 4.b Persistent Uniform Resource Locator (PURL) 4.c Uniform Resource Name (URN) 4.d Digital Object Identifier
35ChallengesCopyright / rights management 5.a Usage tracking 5.b Identifying and authenticating users 5.c Providing the copyright status of each digital object, and the restrictions on its use or the fees associated with itPreservation6.a Preservation of the storage medium 6.b Preservation of access to content
36ConclusionThe concepts of Digital and Virtual libraries are actually services added to the traditional libraries wherein the resources which can only be utilized with computers.We hope digital libraries will coexist with traditional libraries whether within them or as separate entities. However the role of professionals will be drastically changed in digital environment.Digital libraries have customers instead of users and provide pull and push information delivery methods.
