Design and Implement of Digital Library: an overview

Abstract

Several terms have been coined at different times to represent the concept of library without books, Libraries having influence on computer readable format or having access to influence on digitized or digital format. The terms which have been in vague at different times include: Paperless library, electronic library, virtual library, libraries without boundaries and now it has been moved to digital libraries. The tenn digital library on one hand, is used to refer to a system or application whose functions are chiefly to extend electronic access to material available in a conventional library to a remote user. On the other hand, it is used to describe both commercial and academic systems designed to enable electronic access to a large collection of electronic documents to authorized users. The term's digital library and electronic library are used interchangeably and synonymously. The term "virtual library" or "library without walls" usually refers to the meta resources, subject portals that extend virtual accessibility of digital collections from several diverse sources without the users even knowing where the resource actually resides. A virtual library wuld potentially be enormous, linking huge collections from all around the globe, or it could be very small, consisting of few hundred links to digital resources maintained by an individual. The hvbrid librarv is in the continuum between the conventional and di-ei tal libraries where electronic and paper-based information sources are used alongside each other. The challenges associated with the management of the hybrid library is to encourage end-user to provide information in variety of formats and from a number of local and remote sources in a searnlessly integrated way. The hybrid library aims to bring a range of technologies from different sources together in the context of a working library. In effect a hybrid library maintains all or its major parts of its collection in a digitize form as an alternative to supplement the print material currently found in Libraries. It has a web-enabled computerized catalogue (WEBPAC) accessible through the Internet and most of the in-house services like acquisition, books processing circulation are computerized. A hybrid library has a strong presence in the internet with a home page for the library providing an integrated access interface, not only to digital collections available locally, but also to the other commercial and non-commercial web-based digitized collections across the world.
