Digital Library Collection of electronic resources that provides direct/indirect access to a systematically organized collection of digital objects. Hybrid Library Provides 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 Library Access to electronic information in a variety of remote locations through a local online catalogue or other gateway, such as the internet History International Perspective Vennever Bushs Memx Machine, 1945 Invention of Internet 1983

4. Universal and unlimited access Contents will be in digital format which can be utilized only with the help of computer Contents in textual, image, sound and video form Collection to connection
Principles of Digital Library Development 1. Expect Change 2. Know your contents 3. Involve the right people 4. Design usable systems 5. Ensure open access 6. Be(a)ware of data rights 7. Automate whenever possible 8. Adopt and adhere to standards
9. Ensure quality 10. Be concerned about persistence Components of Digital Library Types of Digital Libraries 1. Stand-alone Digital Library (SDL) 2. Federated Digital Library (FDL) 3. Harvested Digital Library (HDL)
Stand-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 selfcontained - the material is localized and centralized. The ACM Digital Library IEEE Computer Society DL
Federated 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. Networked Digital Library of Theses & Dissertation Bibliographic Navigation Tools for Digital Libraries
SCOPUS ELIN Knowledge Cite Library Database Advisor OCLS FirstSearch Harvested 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) 1. A HDL holds only metadata with pointers to the holdings that are "one click away" in Cyberspace. 2. Developed by Library Professionals, or Computer Scientists Four Corner Stones of Digital Library Community

6.a Preservation of the storage medium 6.b Preservation of access to content Conclusion The 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.
